The Clinton camp must be concerned. Several Democrats up for election have distanced themselves from what could turn out to be reverse coattail syndrome. Mostly such feelings are kept quiet for fear of retribution from the Clinton machine.
Meanwhile Obama is proving to be a stronger candidate then anticipated. Now, Oprah has joined him and rallies are selling out.
Then, there are the campaign ads against Hillary that are coming from the "liberal activist" groups, one of which, Democratic Courage, has accused Clinton of making policy decisions on the basis of polls, not convictions. Their ad should launch today.
Hillary may have bitten off more than her canines can handle this time.
