The difference between the "smears" against the President and Mr. Romney is that Obama is clearly hiding something and Mr. Romney is not. Mr. Obama could diffuse a lot of the rumors if he were forthcoming about his college records, his Selective Service registration, his odd social Security number and a birth certificate that looks like Dan Rather produced it.
Maybe Obama was actually born in this country, but there is something he doesn't want the world to see.
The eligibility issue will soon become moot, anyway. We owe it to ourselves however, to develop a better process for vetting Presidential candidates. Many of the illegal immigrants have more convincing phony paper trails than the President's.
