Need a definition of 'Hubris'?

You need look no farther than the acts of the self-appointed, self-anointed, GOP aristocracy of Dearborn County in trying to nullify the choice of the people in the primary. The bitter taste of defeat might explain Vera Bennings' mean betrayal of the voters, but what about the rest of the gang? The consensus I am hearing is that these folks and their friends are the ones that stand to gain the most from unbridled development so they went shopping for another candidate to champion their bottom line. When these dogs lay down together you can bet we ALL wake up with fleas - if we let them. Ironically, the only way to remind these BIG men of the GOP that they are answerable to the public for public policy is to vote for the REAL Republicans that were selected in the primary.
