This is close to the result that I expect. Granted, it's gravis, but I don't think this poll is inaccurate.
It'd be a shame for Donnelly to go, though. We have way too much polarization in Congress, and Donnelly is one of the few people who works with the other side. Braun looks like he will just be a reliable Republican vote, which we already have far too much of in Congress.
You must be kidding. You say you do not like polarization, but you support most of the Democrats. If anything will create massive polarization, it would be a Democrat Senate driven by a Trump hating Democrat base squared off against Trump.
Please point out substantive examples of Donnelly working with Republicans.
