Yes. And not because of their politics, but because she's objectively a terrible candidate. She might blow this election yet, when any remotely competent Democrat would have it in the bag.
You know that hypothetical polls only had Obama doing a few points better, right? And that's while he was floating above the fray for a while while Hillary was subjected to the Republican hate machine for over a year.
Some of you guys seem to have a hard time grasping that 45% of the country will vote for any Republican under any circumstances. Secondly, the Republican hate machine/attack machine was not going to roll over and die if Dems nominated anybody else. And lastly, the media has a vested interest in forcing/manufacturing a horse race under any circumstances.
NO candidate would be a lock against Trump.
