Not a very good idea, considering what a shite-show the Republican Party has become. But what if it was Mitt Romney, who is a dedicated never-Trumper now. If the two mainstream Parties are almost identical (as Chunky claims), then this would be the mainstream Parties versus Trump. Would you vote against Trump in such a case?

What Biden needs to do is to have a VP from the Left, like Warren, to bring the Party together. If he can get the Left and the Center together, he can probably get enough Independent votes to win. Fail to attract either Left or Center and he loses.
