I would hope that most people would feel that what is of utmost importance is getting that abomination out of the WH as soon as possible/practicable. But I'm not this confident in Biden necessarily pulling it off. My concern is mostly around whether he mobilizes people to the polls. Once you give up on the 30% of the electorate that's basically deplorable, it comes down to driving massive turnout. When turnout is high, Democrats win. People like Joe Biden on an "aw shucks" way but is he really going to electrify crowds and get people to stand for hours and canvass like they did for Obama? I have my doubts.
As much as we talk about getting Trump out, if there is any chance at taking back the Senate, it would be a dream come true. It's actually more important in the grand scheme of things.
