Social scientists call this the mobilization of bias. Marxists refer to it as the establishment of cultural hegemony. More plainly, it is a common trick pulled by Team Obama any time they are in a jam: Define your opponents in such a way that their views are not really taken seriously.

Of course, politicians are always trying this stunt. It makes sense to convince fickle swing voters that the opposition is just no good. Yet Obama’s attempts to mobilize bias stand out, for two reasons.

First is the total commitment to the strategy. Listen to any Obama flack long enough (usually just a matter of minutes), and he or she will reference how extreme the opposition is. Last month when discussing entitlements, Jay Carney said the president was looking for the “common-sense caucus.” And, of course, the media echo this: Last week Politico repeated the “common-sense caucus” phrase to report on the president’s golf game with Republican senators. The result is to paint conservatives as so far outside the mainstream that there is nothing that this president can do with them.

Second is the hypocrisy behind the tactic. This, after all, is the president elected because he promised to bring fundamental change to Washington. In The Audacity of Hope, Obama goes on at length about respecting the views of those who disagree with him, especially on abortion. Instead, we have sustained partisan warfare and a first-ever presidential address to Planned Parenthood, in which the president proclaims that the people whose views he once professed to respect are trying to return America to the 1950s.

His disclaimers lauding sensible centrism aside, Barack Obama is the most partisan president since at least Richard Nixon, and maybe even since Harry Truman. He seems to have a visceral dislike of his opponents, deep in his bones, and his political strategy since the spring of 2008 has been to win by disqualifying them altogether.
