one-twenty-oner 

Anyone that was of the opinion that everything was OK with the US under the unrepentant Bush administration, but suddenly the day after Obama's inauguration (1-21) government was too big, taxes too high and all was wrong with the government.

Rush Limbaugh and Republicans supporting Bush and his cronies and exhorting us to blindly support "The President" but now blame President Obama for all of the country's ills and want him to fail. Classic one-twenty-oner mentality.
