Well, sabotage may be too strong a word, but this is telling:
Republicans have opposed a lion's share of stimulus measures that once they supported, such as a payroll tax break, which they grudgingly embraced earlier this year. Even unemployment insurance, a relatively uncontroversial tool for helping those in an economic downturn, has been consistently held up by Republicans or used as a bargaining chip for more tax cuts. Ten years ago, prominent conservatives were loudly making the case for fiscal stimulus to get the economy going; today, they treat such ideas like they're the plague.
Traditionally, during economic recessions, Republicans have been supportive of loose monetary policy. Not this time. Rather, Republicans have upbraided Ben Bernanke, head of the Federal Reserve, for even considering policies that focus on growing the economy and creating jobs.
At some point, Obama has to stop sounding defensive on the faltering recovery and start pointing to who is actually responsible.
