After impeachment: the 2020 election--Stan Greenberg; plus Jeet Heer on Hunter Biden and Eric Foner

Could the Republican defense of Trump in the impeachment proceedings open the door to a watershed victory for Democrats across the board? Even before Nancy Pelosi finally agreed that it was time to begin impeachment proceedings, the Democrats’ prospects for a sweep of the 202 elections were good. That’s what Stan Greenberg says -- he’s a longtime pollster and adviser to Democratic presidents from Clinton to Obama. He’s also a bestselling author, with a new book out – it has the wonderful title 'R.I.P. G.O.P.' Also: Jeet Heer of The Nation magazine considers the Republicans’ defense of Trump – that Joe Biden’s son Hunter Biden really was corrupt in his dealings in Ukraine, and that he really did influence his father’s work as vice president, and so Trump was right to ask the president of Ukraine for more information. Plus: historian Eric Foner talks about voter suppression and the right to vote, about who gets to be a citizen, what rights undocumented immigrants have, and about the history of mass incarceration--and how they all relate to the 13th, 14th and 15th Amendments, part of the country’s attempt to redefine citizenship after the end of slavery. His new book is 'The Second Founding: How the Civil War and Reconstruction Remade the Constitution.' how the New America is Dooming the Republicans.
