The Democrats are in mourning and don't have the heart for this fight.

Let's not overlook resources here, either. The GOP is presumably still in much better shape financially than the Dems, before the inevitable Prez and VP fundraising swings. Do the Dems want to spend untold millions to maybe hang onto one more seat in the minority? I dunno.

I was getting at that point, too. "Having the heart to fight" meaning "having the heart to do all the things you'd normally do to win a race like stumping, organizing, buying ads, etc."

No, they don't want to do it. I wouldn't be surprised if they didn't.
