Trump and his grotesquely inept campaign - except for the last 3+ weeks - would be at the top of my “blame list” should Clinton win. Our shockingly inept/gullible electorate would come in second place on my list. Our ham handed “go along” Republican congressional leadership would have to get their share of the blame for pissing off/frustrating Repubs/conservatives to the point they saw fit to nominate a man ill equipped/ill prepared to run an effective campaign even against a Dem candidate bogged down and under criminal investigation for espionage and corruption.
Blaming the Bushes/Romney? - no one gives a damn about how the Bushes/Romney voted or that they didn’t support Trump, they are yesterday’s news. If Trump loses it won’t be because of what these people did or didn’t do. Glen Beck? - hell, most people in the US don’t even get his station.
Trump himself destroyed what momentum he had coming out of the convention by gratuitously/insanely attacking Cruz the morning AFTER the convention, verbally attacking Cruz’s wife for good measure and repeating the wild allegations he had previously directed toward Cruz’s father. BTW - my guess is there were many women who washed their hands of Trump the minute he personally attacked Carly Fiorina’s physical appearance during one of the early debates - this kind of crap by Trump played into more recent narratives about Trump’s view of women. His attacks on Cruz’s wife was not helpful either. When the dust settles, women will have played a major role in this election.
There are so many examples regarding Trump’s missteps and the “clean-up” required by his surrogates that it is impossible to chronical them all.
A candidate with more discipline and communicative touch - one who didn’t dig himself a hole every other day for much of the campaign - would have won this election. He was on the correct side of the issues and running against a widely known to be corrupt opponent. No, IF Trump loses - and we still don’t know that he will - he must be given the lion’s share of the “credit”.
Hopefully he will still prevail on Tuesday and we won’t have to learn the hard way that without a skilled messenger sometimes the message itself isn’t enough.
