Sure, it's a good strategy for their de facto goal of a narrow loss with tons of funds raised and guaranteed tons of fundraising for 4 years, brunches are expensive. Second best is a narrow win because then they've gotta come up with a bunch of excuses for not doing anything.

Assuming that the Dem candidate has been locked-in, you want the GOP candidate to be Trump. Of course, Dems could just nominate someone good, but that is probably impossible. Also, if a Dem loses to an unpopular Republican, this is great for the Dem party in the long term, they've got 4 years of doing nothing, except fundraising.
