I don’t love him as a candidate. I’m speculating on what may or may not be the most realistic path to the WH.
So your speculation is that the most realistic path to the White House is to support the republican candidate who supports the democrats?
Given your speculation, it could be said that the truly realistic path must be to support the candidates who support the democrats the most. And everyone knows the democrat candidates support the democrats the most. Need I finish? Taking your ridiculous speculation of a so-called "realistic path" to its logical conclusion -- people should vote for the democrat.
