There are a couple of problems with applying this description to today's RINOs.
1) They don't get 75 or 80 percent of anything. They're lucky if they get anything at all.
2) Half the time, they don't even ask for anything. Eighty percent of zero is zero.
3) They never come back to fight for the rest. They grovel for the pittance they're given, then slink away and gobble down the Democrats' table scraps.
4) "Radical conservatives" are the only folks in the GOP these days that have any notion of principle. The rest are accommodationist cowards, opportunistic hacks, or Democrats who took a wrong turn during the credentialing process.
While lining their own pockets.
