Running for Senate and President

[Padfoot]

Senators Biden, Hagel, and Kerry are all currently being talked about as possible Presidential candidates and are all up for re-election in the Senate in 2008.  Should they choose to run in their party's Presidential primary will they be allowed to run in the Senate primaries as well?  I know that this is an option in some states but I'm not sure which ones.  (The states in question would be Delaware, Massachusetts, and Nebraska).

In addtition, Senators Brownback, Clinton, Dodd, McCain, and Obama are not up for re-election but are all considered 2008 Presidential hopefuls.  Should one (or two with a VP) of them win in the general, how and when would they be replaced in the Senate?  Governor appointment or special election?

The only example of this I'm aware of was Joe Lieberman running for Vice-President and for re-election to the Senate in 2000.  As I recall, there was some unusual set of laws in Connecticut that allowed him to do this.

Kind of lame, really; he was more or less conceding that his ticket couldn't win the Presidential race, and needed a backup plan.

That's because Bush had a small to sizeable lead in almost all polls throughout much of the campaign. I remember watching NBC News just about every night during the height of the campaign, and a picture of both Bush and Gore would come on the screen, and one would go to the top of the screen, the other to the bottom. I remember seeing it many times, and only once remember Gore going to the top.

As we know today, those polls were correct.

Not exactly.  Gore did win the popular vote, remember?
