Well, according to many here if you don't vote RINO you're a 'rat.
RINOs have no more special magic that the Democrats and progressives. It's more that if you vote for any other party you're stupid!
Would you rather vote for someone who tells you that she's gonna tax you out of your socks? Or for someone who might do the same but promises not to?
In the old days, given that Hobson's choice, it would be considered a no-brainer.
