I don't get it.

Why should the GOP push for an electable candidacy at any cost? Isn't it better for them to have their cleansing experience through a totally imploded Trump candidacy, have some navel-gazing afterwards, and start anew? Why the obsession to win elections here and now, regardless of the longer-term consequences?

Don't those guys have actual think-tanks to do the thinking for them, for the sake of avoiding tanking?
