How dumb is too dumb?

The Phactor remembers telling a conservative colleague that no one dumber than Reagan could ever be elected president, and then along came "W", and now people are encouraging Texas Gov. Rick Perry to run for president, and as put by Bill Maher, he makes "W" look like the smart one. Apparently there is no bottom threshhold at least for a discouragingly large segment of our electorate. This whole crop of candidates is so depressingly bad, and that's why, even though quite opinionated, the Phactor generally stays away from blogging about politics. It gets me down. It ruins my day.
