Great post by Ed Morrissey at redstate.com.  So far, President Obama has avoided campaigning alongside Democratic candidates seeking reelection this fall.  Could today’s CBS poll showing Obama’s approval sinking to 44% be the reason why?  Probably!  In this same poll, only 34% support ObamaCare.  Ouch!  But in spite of its obvious unpopularity, President Obama continues to needle “Republicans Over Calls to Repeal Health Care Overhaul.“  The President may regret this challenge come November.
