If President Donald Trump has already made fateful choices in the new coronavirus crisis, wait for what's to come. Trump appears unwilling if not unlikely to wait on the advice of medical professionals before nudging American society back to life. It's as stark and bleak a choice as any president can face: human life or economic life. Guest: Ron Klain, former Ebola response coordinator for President Obama

Tuesday's races marked big wins for the former vice president, whose delegate lead is now in the realm of being virtually insurmountable. Meanwhile, President Trump’s administration looks for solutions as cases of COVID-19 continue to spread across the country and the economy hangs in the balance. Guest: Former NJ Governor Chris Christie

The end is in sight for the Democratic primary campaign. The next move in this race belongs to Sen. Bernie Sanders, and him alone. But it's looking like a quieter close all around -- and not just because public rallies are off for a while and Sanders chose not to speak Tuesday night. A range of factors are pointing toward a cleaner and earlier exit by Sanders than anything the party witnessed in 2016. Guest: ABC News' senior congressional correspondent Mary Bruce

This is now a two-way race for the Democratic nomination. Former Vice President Joe Biden's huge Super Tuesday reorders the race but doesn't come close to locking anything down. Sen. Bernie Sanders and the progressive movement now regroup, with an intriguing series of states up next, even as California votes still roll in. Guest: David Plouffe, campaign manager for Barack Obama's successful 2008 presidential bid

In this special edition of "Powerhouse Politics," co-host Rick Klein speaks with Rep. Jim Clyburn (D-SC) about his recent endorsement of Joe Biden and looks ahead to Saturday's South Carolina Primary.

Powerhouse is on the road this week, coming to you from Charleston, South Carolina, site of the next Primary. If Joe Biden goes down, he won't go down alone. The former vice president has company as he enters the last few days of his must-win state, out of a messy debate that showed the conflicting impulses in a crowded field. Guest: Biden campaign adviser, Anita Dunn

Michael Bloomberg gets his very expensive wish in Las Vegas Wednesday night: a Democratic debate where he can draw direct contrasts with his rivals -- Sen. Bernie Sanders in particular. But Bloomberg will have company in making arguments around electability and practicality. And Sanders could have even more company in blasting the billionaire former New York City mayor and his long record running a complicated business and an even more complicated city. Guest: Former Senator Harry Reid (D-NV)

Former Vice President Joe Biden didn't stick around in New Hampshire to see how far he fell in the final votes. A clean New Hampshire win by Sen. Bernie Sanders provides little clarity in the race. Former Mayor Pete Buttigieg comes out of the first two states with two more delegates than Sanders, and Sen. Amy Klobuchar’s surprise finish puts her in renewed contention, too. Guest: Lis Smith, senior advisor for Buttigieg 2020 campaign

The Iowa caucus. The upcoming New Hampshire primary. The State of the Union. Impeachment. February has been a busy month in the world of politics -- and "Powerhouse Politics" breaks it all down. Guest: Brian Fallon, executive director of Demand Justice and former press secretary for Hillary Clinton's 2016 presidential campaign

As the Iowa caucus nears, former Gov. Howard Dean sits down with "Powerhouse Politics" to discuss what to expect. Guest: Former Gov. Howard Dean

Political attention is divided these days and will remain so, particularly as uncertainty about witnesses leaves the possibility of the Senate impeachment trial spilling into voting season. Guest: Tim Miller, author and former spokesman for the RNC

History may not remember that Senate Majority Leader Mitch McConnell agreed to spread impeachment arguments over three days instead of two and to let the record from the House to be admitted as evidence in the Senate. But the fact that McConnell budged is a reminder that the history of the impeachment of President Donald Trump has yet to be written.

Tuesday night in Iowa was a status quo debate in a world where a whole bunch of campaigns like their status. Four candidates have realistic shots at winning Iowa, while others are still hoping to make a mark; polling stability has actually created uncommon fluidity 19 days out. Meanwhile, the impeachment of President Trump moves to the Senate for trial. Guest: Former Senator Trent Lott (R-MS)

Among the many uncertainties to confront the 2020 Democratic field, add a big one: America is now functionally at war. It will now be a wartime primary campaign, under clouds of impeachment, in the race to replace a most unpredictable president. Guest: Sen. Chris Murphy (D-CT)

On this special New Year's Day edition of Powerhouse Politics, Jon and Rick take stock of the narrowing field of presidential contenders and look ahead to the next few months on the campaign trail. Then, they're joined by ABC News reporter Beatrice Peterson who is embedded with the Buttigieg campaign.

On this special edition of Powerhouse Politics, our political roundtable looks ahead to the 2020 race and what the future holds for the newly impeached President of the United States. Guests: ABC's Aaron Katersky, ABC News Deputy Political Director MaryAlice Parks, with Galen Druke and Clare Malone of FiveThirtyEight

If you're looking for a moment of clarity, you could do worse than this day for the history books. In the relatively short life of the current impeachment push, political perceptions have shifted far more than the basic facts ever have. As the foregone conclusion becomes reality with Wednesday's pair of House votes on articles of impeachment, events have cemented the partisan divide and party discipline as perfectly as any issue can. Guest: Sen. Dick Durbin (D-IL)

On one hand, President Donald Trump is facing articles of impeachment. On the other hand, the president has seen some of his biggest legislative wins since he took office. As 2020 approaches, how should potential voters make sense of this? Guests: Trump 2020 Campaign Communications Director Tim Murtaugh and Sarah Isgur Flores of "The Dispatch"

Senator Kamala Harris makes an early exit from the 2020 contest. Yet, for all the big-name busts, Democrats appear to be no closer to uniting around what they want in a candidate. Meanwhile, President Donald Trump is closer than ever to impeachment, with the House Judiciary Committee's first hearing today.

Former NYC Mayor Michael Bloomberg has proven that $37 million -- his week-one advertising bid - buys you a piece of the conversation. His new rivals in the Democratic primary are incorporating him into their stump speeches, preempting his arguments by augmenting theirs. Guest: Neal Katyal, author of "Impeach: The Case Against Donald Trump"

What if a debate happens where the candidates would rather be debating someone else? The main event, arguably, is playing out further north, in public impeachment hearings that continue for at least two more days and threaten to consume far more campaign time. Guest: Former Massachusetts Governor, Deval Patrick

It's the first day of the historic public hearings on the impeachment of President Donald Trump. Democrats called two star witnesses to testify about the president's conduct -- and whether Trump betrayed his oath of office by withholding military aid to Ukraine. Guest: ABC News Correspondent Aaron Katersky

It might just be that election results speak louder than impeachment revelations. For all the caveats of an imprecise barometer, and those inevitably pointing out Kentucky Gov. Matt Bevin's flaws, Democrats walk away from Election Day 2019 with more votes in most closely watched contests -- including a 5,000-plus vote lead as of Wednesday morning in the race for governor of Kentucky. Guest: Senator Sherrod Brown (D-OH), author of the book, "Desk 88: Eight Progressive Senators Who Changed America"

The threats to President Donald Trump are multiplying. The responses from the president, meanwhile, are narrowing -- and pushing his allies in uncomfortable directions. Those offering potentially damaging information and testimony now come from inside and outside of Trump's own party, his own administration and even his own White House. Guest: Newt Gingrich, former Speaker of the U.S. House of Representatives

As the World Series returns to Washington for the first time in 86 years, Jon and Rick check in with Mike Rizzo, the president and general manager of the Washington Nationals. Rizzo talks about what baseball means to Washington, the secrets behind the success of Juan Soto and Ryan Zimmerman, and how he watches a baseball game.
