Alternate Aftermath of 2004 Senate Elections

[Senate Minority Leader Lord Voldemort]

In reality, Republicans picked up senate seats in six states, Democrats two.

-Let's say Tom Daschle scraped by with a 2002 Tim Johnson-style victory.
-John Breaux ran for reelection and won in Louisiana.
-Zell Miller (ew) ran for reelection and won in Georgia.
-Bob Graham ran for reelection and won in Florida.
-John Edwards wasn't on the VP ticket and won reelection in North Carolina.

Senate Republican Majority at 50-50, with Cheney the tie-breaking vote.

How large and bloated does the Democratic majority get between the 2006 and 2010 elections?
How is the 111th Congress different with Daschle as leader as opposed to Reid?
How hard is it to corral Zell Miller into voting for Obamacare? Or will his vote not be needed?

You're assumptions about Miller and Edwards are stretches, to say the least.

I know Edwards' seat would have flipped anyway, he barely won election in 1998 I think. And Zell Miller was a loose cannon, he was basically a Republican through and through. Pretty much useless to Democrats in the senate.

But this is a "what-if" scenario, after all.
