Don't know the answer to that, but it's the same behavior we saw when Liberal Dick (Riordan) ran. Dreier was slobbering all over the place for Riordan.
"RINO" is a term used by bitter ultra-conservatives who are more interested in ideological purity than getting Republicans elected, and influencing the more liberal members to vote in a more conservative fashion.
In other words, people who want it all, right now, and not some now, with a chance for more later, and end up getting nothing but their political nightmares come true. . .
