Democrats capturing the House but not the Senate (most likely scenario) could fairly be seen as a repudiation of Trump, probably because of what appears to be much stronger engagement in the election, primarily by women and millennials. But a squeaker in the House and/or Senate by the GOP is a “confirmation”? Since we don’t “get” to vote for him this year, all we have are the polls. And the majority of people in this country disapprove of him, as a President and a man.
I can safetly say that Trump will most definitely not blame himself if the Rs lose either the House or Senate (or both). I can also safetly say that he will take full credit if he keeps both chambers Republican majority.
I think that the buck stops somewhere between the start of Hillary’s driveway, where she leaves her recyclables on Monday nights, and her front door, because there’s no way that Trump is building up the courage or the fortitude to place the blame directly on her front door mat like the UPS man, because what if she opens the door?
