The right wing spent a lot of time and money last year convincing seniors (erroneously) that the recently-passed health care reform legislation would undermine their Medicare benefits. Political operatives know that the elderly are more likely to vote than younger people, and they are very concerned about any potential cuts to entitlement programs (because they rely very heavily upon them to maintain their standard of living).
So it was very foolish (but deliciously ironic) of Scott Walker to include cuts to Wisconsin's popular Seniorcare program in his budget. This particular issue is driving a wedge in his control of the State Senate. He might have been able to keep Darling and Hopper in line, if they weren't facing recall campaigns thanks to the shenanigans of the Fitzwalkerstan administration.
It seems that the Governor has been hoist by the Teapublicans' petard.
