I don't know the person's name, but I think I know who told Harry Reid that Mitt Romney didn't pay taxes for 10 years.  I think it was the same person who spread equally unsubstantiated rumors about President Obama's birth certificate. And why not? It's all the same baseless tale-bearing that degrades politics and breeds the mistrust which is making good governance increasingly impossible.

"An investor said"... An "anonymous caller" claimed... "I have it on good authority that"... "I am not certain that it's true, but..."  This is the stuff of the worst political cultures in the world - cultures which trade in fear instead of results, and picking at old wounds instead of healing them.

The fact that a sitting senator, and the Majority Leader no less, could engage in rumor mongering and innuendo at this level may be without parallel, at least since the era of Joe McCarthy.  And as with then, this is behavior of which Sen. Reid, all those who support him, and even those who remain silent in the face of his egregious behavior, will come to be ashamed.
