I think the Republicans are going to nominate someone like her in the next election, and that it'll be a worse loss than the previous one, and then they'll start to turn the party around, by starting to divorce the party from certain old ideas that are just holding it back, while keeping the ideas that make them more politically flexible
With a fresher Republican party, the face of American politics could become much more civil (not saying the lack of civility is their fault, but if one party moves beyond this culture wars crap, then the other won't be able to use it either)
