With the GOP in serious danger of losing control of the Senate, every contested seat counts, and if the GOP picks up a seat from a Democratic incumbent that would mean the Democrats would have to pick up two extra seats to gain an advantage.
Poster Comment:
Trafalgar has Trump winning Michigan and Wisconsin. He said the Republican Senate candidate in Michigan is polling ahead of Trump so that is a pickup of two. We will need those votes to confirm all the judges and others like replacements for Barr at AG and Wray at FBI.
