Although some say the Senate majority leader has gone too far, all signs appear to suggest he’s not backing down.

The “one person who couldn’t care less” about being criticized for his attacks is Reid himself, points out Politico, noting the senator doesn’t plan on stopping the attacks. As far as Reid sees it, this is a winning issue for him because it’s keeping attention on Romney’s taxes. Besides, Reid’s aides insist the majority leader really believes his source, who is allegedly a longtime investor at Bain Capital.
