Then i guess Barbara Lett-Simmons woudnt abstain and vote for Gore
270-268
No abstaining means, you don't vote so Bush's 271-267 victory was 271-266, in their scenario, she doesn't abstain, because Gore has 269 votes, not 268
Also with the House vote, I see Mike Castle abstaining for political cover, especially after Bill Roth's landslide loss
I see all Dem delegations go for Gore, including AR, WV, and MS, of these only MS is concerning, and Shows and Taylor would easily win reelection anyway
So, it's really 27-18, with 5 abstentions (Castle+the 4 deadlocked delegations)
The Senate is interesting, it would deadlock 50-50
Meaning that Dennis Hastert would be VP
But I think at least 1 or 2 of the following cross party lines and vote for the moderate Lieberman:Jeffords, Campbell, Fitzgerald, Lugar, Snowe, Collins, Hagel, Smith, Specter, Chaffee, Bennett, Warner
Ben Nelson and Zell Miller are the only possible Democratuc defections, and I doubt either defects
So we have in order of likelihood
Bush-Lieberman administration (still, pretty much the same as IRL, because Lieberman was a hawk, I think he would actually switch parties ITTL, because of the growing importantance of foreign policy, also Nancy Johnson probably fills his seat, she would probably beat Ned Lamont in 2006, and then lose to Murphy in 2012, but Senator Nancy Johnson means a 59-41 Dem majority during the Obama years, changing history forever)
Bush-Hastert adminstration (Here, the Senate deadlocks on party lines, and Speaker Hastert becomes VP, so Dick Armey becomes Speaker, but in 2003, Tom DeLay becomes Speaker, his scandals become a distraction to the GOP and the 2006 midterms are even worse, with Demixrats picking up some missed low hanging fruit (Gerlach), also Harold Ford probably becomes a Senator (only to be Blanched in 2012). So, then Roy Blunt is Speaker, and would be serving as Minority Leader in 2010, ITTL, I doubt, that he runs for Senate, it's basically a redux of the 2012 primary and Todd Akin happens two years earlier, Akin loses by double digits to Carnahan. Also in 2010, as Dems have an extra seat, Scott Brown's victory still leaves Dems with filibuster-proof majorityMeaning that the Senate is 55-45 in 2010, with two extra Dem seats. McCaskill goes down in 2012 to Sarah Steelman with no Akin, and Ford is Blanched, everything else is OTL. Everything else is same as OTL, except Carnahan wins reelection in 2016, over Ann Wagner. So, the Senate balance is 51-49, ND Doug Jones victory, deadlocks the Senate.
Bush-Cheney (requires Nelson and Miller to cross party lines, OTL, except Nelson and Miller likely buck party more, Miller may actually switch to Republicans, offsetting Jeffords switch
