On the Internet, there is a famous principle that has come to be known as Godwin's Law. Named after columnist Mike Godwin, the Godwin Law states that as Internet discussions grow longer, the probability of a comparison involving Nazis or Hitler (whether legitimate or illegitimate) approaches. Anyone who has spent any time browsing the blogosphere can verify Godwin's Law.
Anyone who pays any attention to the trials and tribulations of President Obama can recognize the existence of another law. Call it Shapiro's Law: As any conversation involving an Obama supporter grows longer, the probability of the Obama supporter citing the failings of President Bush approaches. In fact, Obama supporters rarely wait longer than 30 seconds before referencing President Bush's shortcomings. President Obama himself talks about President Bush more than FDR, JFK, Lincoln and Martin Luther King Jr. combined.
Why do Obama supporters believe that President Bush's weaknesses excuse President Obama's total incompetence? When you mention that President Obama has driven the national debt to unprecedented levels, they mention that the Bush administration spent too much, too. When you mention that President Obama has nationalized industries and seeks to subvert private health care, they mention that President Bush passed an expansion of drug benefits and sponsored bailouts of the financial firms.
This is utterly illogical.
If O.J. Simpson had committed double-homicide, then cited Ted Kennedy's manslaughter as justification, we would have scoffed. Yet we are supposed to accept "Ignore Obama, Bush was horrible" sloganeering as the apotheosis of argumentative rhetoric.
This is an administration that does not deign to make logical arguments. This is an administration that calls names and levels slurs at its opponents rather than challenging them on logical grounds. This is an administration that embraces the polarizing politics of racial pandering and class warfare while claiming a nonexistent high-mindedness.
