What happens if Lieberman becomes president in September 2001?

[Mr. Morden]

Riffing on this idea:

Gore/Lieberman win the 2000 election, either without a recount, or with a recount that goes their way.  9/11, or some similar 9/11 style attack happens in September 2001, except that in this case, the plot also involves the assassination of President Gore, which is successful.

Lieberman is sworn in as president (the first Jewish president), and the War on Terror begins with a Democratic president....who also happens to be rather hawkish on foreign policy, and not exactly beloved by the party base.  (Though keep in mind, in real life, Lieberman's friction with the party base didn't really erupt in a big way until his 2004 presidential campaign.)

What happens with Afghanistan?  What happens with Iraq?  What happens with issues like waterboarding, Guantanamo Bay, warrantless wiretaps and the like?  How does Lieberman handle these issues, and do the Democratic and Republican parties confront these issues in a completely different way because of the fact that the War on Terror begins with a Democratic president?

And of course, what happens in the 2004, 2008, and 2012 presidential elections?

[Mr. Morden]

I guess, moreso than predictions on the specific elections, I'm wondering what people's thoughts are on whether Lieberman's anti-terror policies would resemble those of Bush's IRL.  And would the grassroots of the Democratic Party have gone along with Lieberman on his anti-terror policies, or would it rip the party apart?

And would the GOP, being out of the White House for so long, start to grow really distrustful of the Executive Branch, and get more isolationist in foreign policy?

[Mr. Morden]

Ok I've been thinking this over.  What if Gore decided to go for OH Instead of FL, narrowly wins it, W. picked Pataki or Engle to broaden his base, campaigned hard in MI, IL, NY, NJ, and PA, narrowly loses all of them, but it's enough to win the popular vote?  He refuses to allow a recount to divide and weaken the country so concedes before recounts.  This makes him look like a graceful statesman to the people and he's generally well-liked.  He campaigns hard for the GOP in 02, 04, and 06.  Could he make a comeback in 08 in a President Gore/Lieberman TL?

Possibly.....who would be GOP nom in 2004? Pataki, Engle, or McCain?

I assume that by "Engle" you guys mean Engler, as in John Engler?

I any case, Engler is my de facto "what if" 2000 GOP nominee if Bush never ran.  In 2004 though, if it's not McCain or anyone else in Congress, then my de facto "what if" GOP nominee would be Frank Keating, particularly if terrorism is still a major issue.
