How about we try for an explanation, instead of an excuse? I know thatīs not very popular amongst the über-partisans on both sides, but rational debate is sometimes feasible, even on this forum.
My explanation is simple enough. The guys in power are always the fall guy. Had it been a Republican congress and the same challenges facing society, the Democrats would have won big last night. Unemployment is high, the economy isnīt exactly doing that great, so itīs only natural that people look for other guys, usually the one promising the most.
Again, has it been the other way round, the Democrats would have been the ones out there promising easy fixes. The nature of politics, I guess.
However, on another note, having a shift in Congress might not be a bad thing for Obama. Now the Republicans will have to share the burden in 2012, they cannot say "Well, we got no influence". Now they have to start coming up with results, so itīs not all bad, seen from a Presidential perspective.
Just my two cents.
