Arizona Debate: Conservative Chickens Come Home to Roost

Most importantly, though, the conservative passion for divisive, partisan, bomb-tossing politics is threatening to permanently cripple the Republican party. They long ago became more about pointing fingers than about ideology, and it’s finally ruining them.

Oh, sure, your average conservative will insist his belief system is based upon a passion for the free market and limited government, but that’s mostly a cover story. Instead, the vast team-building exercise that has driven the broadcasts of people like Rush and Hannity and the talking heads on Fox for decades now has really been a kind of ongoing Quest for Orthodoxy, in which the team members congregate in front of the TV and the radio and share in the warm feeling of pointing the finger at people who aren’t as American as they are, who lack their family values, who don’t share their All-American work ethic.

The finger-pointing game is a fun one to play, but it’s a little like drugs – you have to keep taking bigger and bigger doses in order to get the same high.
