Obama's Drug Use

So the drug-addict Rush Limbaugh insists yesterday that it's time we talked about Obama's drug use (as a teen) and now, of course, John Sununu does as instructed:

A top Mitt Romney supporter went on a rampage against President Obama Tuesday morning, bringing up his teenage drug use and urging him to “learn how to be an American.” [from Talking Points Memo]

Good grief. We suffered (the world suffered) through eight years of the presidency of a man, W, who was a coke-head in college and an alcoholic, and we heard almost nothing about that. Where were these voices then?
