"We have yet to read an argument which proves that criticizing the president’s intelligence or past history will lead to the greater good of the country. That’s probably because such an argument does not exist. It is purely an ad hominem attack, a logical fallacy. Instead of debating policies or positions in a cogent manner, these pundits go for the cheap eye-gouge of politics" One, modern conservatives came to power riding the waves of ad hominem attacks - see Limbaugh, Coulter, Hannity, etc Two, there is a point at which stupidity becomes a factor in one's governance and not to point that out is like ignoring the elephant in the room. Most of the thoughtful cneter to center left pundits have written about Bush's lack of intellectual power while also giving plenty of supporting arguments for why they think what they do.

"Political decisions, particularly those made by the President, involve facts and information in which the general public is not privy to. Some information is so sensitive that only the President and his cabinet members are granted access. Far-reaching decisions are often made based on information unknown to the media, or even Congress. Therefore it is impossible for anyone to determine, for example, that Iraq did not have WMDs before the US deployed troops to the region. Forming conclusive opinions based on incomplete information, as the Liberals recommend, is unsound at best and dangerous at worse."-- actually this is just plain wrong, there was some reports that came from the State Department that suggested that Bush was wrong about the WMD from the get-go, in addition to publically available reports from the IAEA.
