Come on Eraserhead, it's not 2008 anymore. We're allowed to like Clinton again! She'd win a huge landslide as well. It would be political malpractice for the Democratic party not to run her as its candidate.
I heavily doubt it. Just because she's really well liked now doesn't mean she will still be once she's back in the arena of politics. She is in a position where she can be nonpartisan, but once she starts running as a politician again, I have a strong feeling that her favorables will go down (especially once the name recognition of other candidates increases). There is probably a decent chunk of people that like her now that probably will not like her once she's the standard bearer for the Democratic party again.
