Because he can win. The far leftists/socialists that are Warren and Sanders will get rejected at the ballot box. This country is not going to go that hard to the left.
But Biden is viewed as centrist enough. He’s also high on the likability scale. This is why the Dem challengers are going after him so hard in the debates. They know he’s in their way.
But a popular female, progressive candidate like Warren is too much on her own. But she’d bring a lot of energy to the bottom of a Biden ticket. That would be dangerous I think.
I’m just not sure that 1) Biden can stick it out until the actual voting begins and 2) if the enthusiasm for Warren and Bernie will allow Biden to win primaries.
It’ll be interesting to watch. If the Dems want to win, they should nominate Biden.
I think, u r cra-cra.
