Whilst the first paragraph does make some sense, it presumes that in such a situation the Republicans would not conclude it's the style of the candidate rather than his ideas that caused the rout. That might be a little optimist considering that the traditional Republicans' were just as far right economically before and almost as right in Moral issues, but they had a different style of candidate (remember Reagan?).

It might also be a little optimist to expect an absolute walloping of anybody, Republican or Democrat.

That said, it's a valid scenario, though it relies on very low probability events.

The second paragraph is inconsistent with every single thing the Democrats have done in their pre-electoral propaganda, from the whole "vote us or get Trump" (something which wouldn't scare the Right) to the raft of pre-election promises on Left-wing subjects like student debt forgiveness or tightening regulations on giants such as Telecoms a little bit. If they really thought they could win with only votes stolen from the Right, they would be making promises which appeal to the Right, not the Left.

Besides, the whole idea that Rightwing voters would go for the less-Rightwing party rather than the more-Rightwing party is hilarious: why go for the copy if you can get the real deal?

From what I've seen in other countries were Center-Left Parties totally dropped their appeal to the Left and overtly went to appeal to the Right, they got pummeled because the Maths don't add up and, as I said above, Rightwing votes will choose the "genuine article" over the "wannabes".

It's not by chance that in Europe even whilst becoming full-on Neoliberal parties, Center-Left parties maintained a leftwing discourse and would throw a bone to the Left once in a while (say, minimum wage raises) when in government.
