When they can't get their way, meaning when the GOP loses an election, they race to delegitimize the winners. They did it with Clinton, going so far as to impeach him after he won reelection by destroying that old fart, Bob Dole, who lost because he had no personality and no cohesive campaign back in 1996. They did it again after Obama routed another old fart, back in '08, when both Houses of Congress also went against them.
Remember the Tea Party protests of 2010 and the "Party of no"? Those fools acted like the world was coming to an end. Biggest bunch of sore losers I ever witnessed.
And, now, after another ass-beating in yet another reelection campaign, and after losing Senate seats in traditionally red states like Indiana and Missouri, the GOP is once again acting like a spoiled child, this time basically holding it's breath and watching the country turn blue.
They simply cannot abide by seeing a majority disagreeing with them politically. They simply cannot respect the opposition. If they win, they govern as if the opposition does not exist. If the opposition wins, they batten down the hatches and refuse to cooperate in any way shape or form. They are the nullification party.
