This week, after Walker endorsed Cruz, Trump laid into Walker for the performance of Wisconsin’s economy, telling hundreds of supporters in Janesville “he’s not doing a great job.”

Milwaukee County has become Cruz country as conservative talk radio has aligned against the real estate mogul and reality TV celebrity and behind the first-term senator. The latest Marquette Law School Poll found Cruz leading Trump 53-15 in Milwaukee County. Kasich came in second with 22 percent support.

Attendees at Friday night’s event said the vast majority of the crowd were Cruz supporters, which was borne out by the response to the speakers.

Among the Cruz supporters was Christina Bauman, 53, a registered nurse from Waukesha who said Republicans in Wisconsin are supporting Cruz because “we are ground zero for conservatism.”

“People are just fed up,” Bauman said. “We want results.”

Warren Matson, 57, a Realtor from West Allis, said he is undecided, but has been leaning toward Trump after Ben Carson dropped out of the race. However, Trump’s gaffes over the past week, such as reversing a statement that women who receive abortions should be punished if abortion were to become illegal, have raised doubts about Trump. Matson’s wife, Maggie, is supporting Cruz.
