Don’t think so this time.
Everybody doesn’t think so, then it happens. Thanks to gerrymandering and campaign finance rules no matter how much people hate Congress as a whole they always find a way to like THEIR Congressman, which is why Congress can have a job approval rate in the low 10s and a re-election rate in the 90s. The Senate is the only place you see any “real” turnover and even there you’re talking 1/5 to 1/4 of incumbents losing. The Dems will lose seats this year, because it’s a second mid-term, but even this years “blood bath” when you look compare them to the whole will be nothing.
