This truly is the most dysfunctional congress in modern times and that's saying a lot...
Obama has the tools to be a good President and under normal times he probably would be ranking among the best. He's intelligent, pragmatic, and has charisma. Unfortunately you'd probably need a Pit Bull for a president to tame this Congress and even then that might not be enough.
I think the main problem for Obama is that early on the narrow/near super majority they had in the Senate was Fool's Gold. Instead of planning their strategy around just getting a simple majority (use reconciliation if necessary), they kept kowtowing to Blue Dogs and 2-3 Republicans to get a "bipartisan" or filibuster-proof vote. They should have forced Republicans to actually Filibuster on the floor the Stimulus or Healthcare Reform. Instead the GOP just had to give the threat and Dems went retreating. As a result, there are a lot of water-downed bills that still didn't get Republican votes and now Obama's main policies aren't nearly as strong or attractive as they could be.
