High IQ: Do you want another idiot as president?

I did some Google searches. The text was, 'bush idiot', 'clinton idiot', etc. Here are the stunning results:

bush 2240000
clinton 1420000
edwards 1250000
michael moore 1050000
obama 947000
ron paul 918000
giuliani 780000
mccain 769000
romney 660000
fred thompson 536000
kucinich 371000

Especially surprising are the relatively low numbers for Guiliani, Mccain, and Romney, well below Ron Paul. On the other hand, Kucinich is much lower than the others. I have a number of highly speculative theories about this:

1: Republican attack blogs are meaner.
2: Giuliani, Mccain, Romney etc. are more worried about Paul than each other.
3: The people who label others as idiots don't feel that Giuliani et. al. are worth bothering.
4: Kucinich really is less of an idiot than the others.

I am going to define the IQ (Idiot Quotient) of a presidential candidate is 1/(number of Google Hits for 'Candidate Name idiot'). By making the IQ the reciprocal, the fewer the hits, the higher the IQ.

Note that Bill Richardson, Chris Dodd, and Biden all have a higher IQ than Kucinich.
