I don't really like her, but I hate Huck much more than I hate her, so I'd like to see her live long enough to take pull off some kind of ridiculous revenge scheme against him.

He still needs to win an election; so far, he hasn't been elected by any group larger than his home district. The original UK version spanned about 10 years, and Frank has the potential to be President for that long.

Well, if season 3 starts where season 2 left off, he doesn't really have any kind of major political mandate if he doesn't get elected, does he? He has the potential to be up to 10 years in office. Didn't the BBC series cover a time period (in-Universe) of about 10-12 years?
