The Marquette poll is only Republican likely voters.
Wisconsin is an Open primary state - which means that Democrats and independents can vote in the Republican primary. Trump has lots of Blue Collar Democrat Union supporters and independents and Wisconsin has many union workers.
Cruz may be ahead of Trump, but it is a lot closer than the 10 point spread this poll suggests.
A more accurate poll would be of everyone who is likely to vote in the Republican presidential primary, not just Republicans!!!
When has Cruz won an open primary?
If they are only polling Republican voters, I think Trump has a very good shot to win.
5 days are a lifetime in a primary. Trump can easily turn this around. I hate to use this as an example, but Obama was losing to Clinton in 2008 and decided to give a speech on race. Well it worked and that turned Oprah and the kennedy’s towards Obama. I think trump needs to make a speech on woman and bring out the women who work for him in his businesses. And during the speech give his policies that are on his website. I think that would turn this primary back to trump.
It should be framed as a vote against sold-out establishment pols. And then demonstrate that Cruz is not one of them.
