I've never seen a national poll from a reputable source which showed Obamacare with 50% of the public support. For Davis to tell the left-oriented Associated Press (of all people) that Obamacare is "50-50 at best with the public on a good day" (don't exactly know what he means by that, but since he's presumably a Republican talking about repeal, one would think that he's saying that opposition to Obamacare is NEVER more than 50%) is to deliberately downplay the support for repeal at a time when repeal is picking up momentum and thereby undermine GOP efforts when every single voting Republican in House voted for repeal!!! That's stabbing his former colleagues in the back!
Trying to pin this guy down is, as they say, a fool's errand!
