In a national poll, Rasmussen asks likely voters: "In the dispute between the governor and the union workers, do you agree more with the governor or the union for teachers and other state employees?"
The result:
48% of Likely U.S. Voters agree more with the Republican governor in his dispute with union workers. Thirty-eight percent (38%) agree more with the unionized public employees, while 14% are undecided.
Of course, as far as Scott Walker and Wisconsin Republicans are concerned, the only polls that matter are polls of Wisconsin voters, and I haven't seen a reliable pollster release a statewide suvey yet.
