Dave Berri over at the Freakonomics blog has a great post about approval of political actions as a form of party tribalism.
The national debt seems to always trouble the party that isn’t in the White House. When Bush was President (pick your Bush), Democrats were very troubled by the rising national debt. Republicans, though, were relatively quiet. Now that Obama is President, Republicans are extremely worried about the national debt. However, Democrats don’t seem as alarmed.Berri illustrates this further with an anecdote about how Democrat and Republican voters, as groups, reversed their positions when asked if the president is responsible for high gas prices, when the party in the White House switched.
President Barack Obama himself is guilty of this slight. As a Senator, he was quick to blame President George W. Bush for high gas prices, but now that he's in the oval office, he believes oil prices are determined by the global market
This is unfortunately, part of the human experience and we're all guilty of doing this. Our brains are very good telling us that what we want to believe is the truth, and are skilled at making excuses when a few pesky facts get in the way.
