The top fundraiser in the Democratic presidential field was hospitalized with a heart attack, the longtime polling leader and his son sit at the center of an impeachment inquiry, and the one candidate with clear momentum faces persistent doubts among some party leaders that she is too liberal to win the general election…

“What has impressed me about [Warren] is she creates her own weather. She has risen in the polls on her own, not pushing off against somebody else,” said Jennifer Palmieri, a top strategist for Hillary Clinton in 2016. “I hear from a lot of campaigns that she is going to have to answer questions now. Well, I don’t know. She gets asked questions all the time. I’m not sure that confronting her is going to have the impact that other campaigns want.”…

Another major Democratic donor, speaking on the condition of anonymity to describe private conversations, said he and other donors seeking a moderate as a nominee have “zero interest in coming around to Elizabeth Warren.” If she’s the nominee, “we can’t vote for her or Donald Trump” and would sit out the election, he said.

The donor also expressed worries that if Warren is the nominee, her presence would ruin any Democratic chances to win the Senate, because voters would perceive having a Republican majority as “the only way to keep her in check” as president.
