Washington (CNN) -- While 39 House Democrats voted with Republicans on a proposed fix to canceled insurance policies under Obamacare on Friday, sources on both sides said more would have defected without President Barack Obama's mea culpa over the mess. As it is, the vote is an embarrassment for the President, but it could have been worse. Another 18 defectors could have given Republicans a veto-proof majority and ammunition to really pressure the Democratic-controlled Senate to take up the measure. But senior Democratic aides said that might have been possible before Thursday. That's when Obama took action on his own, met with reporters to talk about it, and dispatched his Chief of Staff, Denis McDonough, to Captiol Hill to meet with Democratic lawmakers.
