The Note: Biden and Trump force parties to look inward

President Donald Trump greeted Joe Biden’s entrance into the race with insults.

The TAKE with Rick Klein

For his part, Biden starts his campaign wrangling with his past, including a famous and not-forgotten episode involving Anita Hill and her testimony before the Senate Judiciary Committee during the confirmation hearing for Supreme Court Justice Clarence Thomas. Biden will respond to that and much more in his first interview as a candidate today on ABC's "The View."

Biden has started his campaign by making it explicitly about Trump and what he represents. And Trump is more than happy to return that favor.

But both Trump and Biden are forcing important intra-party conversations into the open. In critical ways, those conversations involve both men squaring off against themselves.

The RUNDOWN with MaryAlice Parks

And then there were 20.

The largest Democratic primary field in decades includes: six women, six sitting senators, six former and current mayors and one former vice president -- for now. Their ages span four decades, and their experience in and out of Washington and executive roles varies enormously.

And there's buzz that the field could grow again with yet another red state Democratic governor contemplating a run.

Nonetheless, the breadth and range of candidates is fascinating. And while it's surely overwhelming to some, it fits a party that has been in a period of renewal and rebuilding since the last presidential campaign.

Maybe it's that soul-searching that makes Biden's campaign feel both logical and illogical at the same time -- a symbol of a day when the party felt strong, but also a symbol of a past. His greatest challenge might be convincing voters that he has a vision for the future.

The TIP with John Verhovek

Five 2020 candidates descend on the state of Nevada this weekend to court a key constituency: union workers.

Former Housing and Urban Development Secretary Julián Castro, former Rep. Beto O'Rourke and Sens. Kamala Harris, Amy Klobuchar and Elizabeth Warren were all slated to attend a convention, put on by the Service Employees International Union and the Center for American Progress, focused on labor unions and economic policies aimed at the working class.

But it was Biden whom one of Nevada's favorite political sons spoke highly of earlier this week, although he stopped short of endorsing him, saying he would wait until after the February 2020 caucuses to make that decision.

"I think Joe Biden can succeed in the Democratic Party of today, I think he's a good candidate. I always boast about my affection for him. I think the world of him," former Senate Majority Leader Harry Reid told reporters on Thursday during a press call.
