The election is pretty much lost as it is.

This is the long term plan. None of the presidential candidates have a snowball's chance in Key West of getting close. But Trump is five more years at most. The goal is not to get an independent to vote Democratic candidate. It's to get them so disgruntled as to not vote at all. There are still a number of red congressional districts in blue states where the congressional arguments against the incumbent is "he supports Trump." Trump isn't going to win New York, but if turnout is light in the state, he could lose a number of Republican Congressmen including one of his greatest supporters, Lee Zeldin (who is currently on his "team" on the impeachment trial).
As for shutting down the government; we know what happened when the Democrats took total and absolute control back with the election of Obama ... almost nothing. The Affordable Care Act barely got passed. Currently nothing of any significance to the Democratic party the House passes will be accepted by the Senate and even then, it's going to be vetoed and die anyway, so ... nothing is actually better than a failed something.
The big thing is that this shuts down the presidential campaigns of every Democratic senator. The good news is, apart from Bloomberg, the other non Senator (Biden) is mostly incapable of taking advantage of that and the whole thing is pouring radiation on his campaign anyway. (Let's see we are up to two sons getting government kickbacks.)
