The crash doesn't happen until May 20, 2009. But it is even worse than IRL. How does he do?
2010: Dems hold onto the US Senate seats they lost OTL (with the possible exception of AR) and gain FL, IA, OH, NC, and NH. Dems make about a 10-15 seat gain in the House (which they held in 2008). As for governors, Dems pick up AK, AZ, FL, and NV, but lose OK, TN, and WY. Dems hold onto the rest.
2012: Dems win the US Senate seats they did OTL plus NV and possibly AZ. They gain a few seats in the House but are likely maxed out. As for governors, they win all their OTL seats, keep NC, and pick up IN. They never won WI in this AU, so the Walker recall election never happens.
Just my guess.
