I don't think she'll ever make it to the White House. Not that I am advocating it, I am not, but there are enough whacko's in this country that I think someone will get to her. Even a few foiled attempts and it will finally sink in that she will never be President and will bow out.
If you refer to assassination attempots, there are several aspects:
1: a 5% plus bump minimum in the polls if someone tries to kill her.
2:Their popularity with assassins should not be a yardstick for their ambition. Plenty of Presidential candidates will ontinue to attract nutjobs, but that doesn't disqualify them regasrdless of party. 3: I'd be more likelty to vote for sonmeone where they were nearly assassinated but carry onn, purely on sentimental reasons. I may not like their politics, but I approve their courage. Any physical attack ona Demo candidate wuill tar the Republicans, even though no one believes it was their doing.
