“We’ll ultimately have a presumptive nominee fairly late. I think it could [help Trump]. It really makes it more difficult because it’s just harder to organize,” said Rep. Dan Kildee (D-Mich.), who is neutral in the race. “Just literally organizing an operation on the ground is hard to do quickly.”…

“If the Democrats are not united, then a strategy of winning the Electoral College could work for the president,” said Sen. Ben Cardin (D-Md.), who has not endorsed a candidate. “The calendar is: We could be doing this in July. And there could be hard feelings afterward. You saw that in 2016. We were not as united as we needed to be. So I worry about that.”

The muddle has left congressional Democrats trying to win the Senate and keep the House increasingly anxious. Majorities of both House and Senate Democrats haven’t yet endorsed, adding to the confusion and evoking the paralysis of Republicans in 2016 as Trump surged ahead of a crowded field.

Some Democrats think the anxiety might not be such bad thing.
