This brings up an interesting point to me, how would the Lewinsky thing have been seen if Clinton had been single at the time? It's still pretty skeevy to have a sexual relationship with an intern, even if you aren't married.
Unless it's an oversight, the fact that she's using the middle initial seems to imply she still had her writing career, since in OTL it's meaningless and was added essentially as a pen name.
That's the logical way to do it. Have a state legalise it, someone challenge that in court and have the SCOTUS decide that banning it is unconstitutional (for reasons of freedom of speech, presumably). The problem is finding a court that would actually rule that way.
They could also in theory vote for someone who isn't eligible to be president (since there are essentially no restrictions on who can be speaker except getting a majority to vote for you), in which case the President Pro Temp of the Senate would become president.
:eek: (although no offence to the girl, but if she lives to be 66 I'll be impressed)
As has been mentioned, the Clintons are probably the easiest family to do this with.
