9%, what does it mean
Currently congress has a 9% approval rating. I don't think honestly that it makes much of a difference. People still like their incumbent senator and reps, so they keep on voting for them. It's "all those other guys" who are the problem.
Also, keep in mind is that this play is straight out of the starve the beast playbook. There's a reason why Republicans are driving the country straight into a hole, this is proving their point that government doesn't work.
