The theory is, the Republicans will win big because people want to say "no" to the Democrats. If so, the Democrats should be kicking themselves — stomping themselves — for going all-out defining the GOP as "the party of 'no.'" These days, no is what people are for.
Rasmussen makes the argument that we will see a lot, that the GOP victory shouldn't be understood as a preference for conservatism:
[I]t would be wise for all Republicans to remember that their team didn't win, the other team lost. Heading into 2012, voters will remain ready to vote against the party in power unless they are given a reason not to do so.
Elected politicians also should leave their ideological baggage behind because voters don't want to be governed from the left, the right, or even the center. They want someone in Washington who understands that the American people want to govern themselves.
