United on deportations, support for Trump, property taxes
We often look at polls for the toplines, the balance of opinion across the full population. But it is important to understand the very substantial divisions in our politics that are masked by that single topline. Today I start a series of posts on what partisans and independents in Wisconsin think. I’m doing them one at a time to stay focused on each party. We’ll come back with some comparisons in the final post. Today let’s start with the Republicans.
Republicans in Wisconsin are most united in support of deporting immigrants in the U.S. illegally, reducing property taxes, supporting President Donald Trump and approving of the way ICE is going about enforcing immigration laws. Between 87% an 95% of Republicans embrace these four topics.
Republicans are also united in disliking the Democratic party, Gov. Tony Evers and his 400-year school funding veto.
The chart shows Republican opinion on 23 topics covered in my Feb. 11-19, 2026 Marquette Law School Poll of Wisconsin registered voters.
The GOP is almost as united on believing that most deportees have criminal records, having a favorable view of ICE, being favorable to the Republican party (though less so than to Trump), and believing that public schools must live within their budgets rather than receive more state aid. Each of these opinions are embraced by 80%-83% of Republicans.
Solid majorities say that the shooting of Alex Pretti in Minneapolis was justified, that immigrants in the U.S. illegally should be deported even if they have been here a long time and have no criminal record and that Trump’s policies will decrease inflation.
Similar majorities oppose online sports betting, and disapprove of the Wisconsin Supreme Court. Only 35% think tariffs are helping Wisconsin farmers, though a similar number think tariffs have no effect. On this topic opinion is less solid than it appears.
Then there is a set of issues that are less consensual with only small majorities: 57% say they are living comfortably and 55% say they are better off than a year ago; 53% approve of the job the legislature is doing and 51% are satisfied with their local public school. And 43% think the benefits of data centers outweigh their costs.
Simplifying, the GOP backs Trump and his policies (with some doubts on tariff effects) and wants to rein in property taxes and school spending. And they don’t care for Democrats or Tony Evers (no surprise there.)
Most important concerns
The priorities Republican have across issues largely mirror the unifying issues above. The top issue concern is illegal immigration and border security followed by property taxes. Those are followed by inflation and the cost of living and taxes more generally.
Further down the concerns, with less than 50% saying they are very concerned, are health insurance and the cost of electricity. Still further down are abortion policy and jobs and the economy. Ranked last is concern over gun violence.
The Wisconsin GOP is strongly united on issues of national politics centered on President Trump, and in state politics concerning property taxes and school funding. Also in opposition to Democrats.
There is less unity on new issues like data centers and online sports betting. And just over half say they are getting along well financially or better than before while there is some significant concern with inflation and the effect of tariffs.
There are other issues not covered in this poll that could also become important in the fall elections, but will await new polling.
