A new opinion poll shows Ted Cruz with an advantage in Wisconsin among likely Republican primary voters, but Bernie Sanders and Hillary Clinton seem to be in a close race.
The data released Wednesday from Marquette University shows 40 percent of likely GOP primary voters support the Texas senator, compared to 30 percent for Donald Trump and 21 percent for Ohio Gov. John Kasich. About 8 percent of respondents were undecided.
The Marquette Law School Poll was conducted Thursday through Monday. The poll's full sample includes 1,405 registered voters interviewed either by cellphone or landline. Results for the Republican primary are based on 471 voters who say they're certain to vote. The GOP sample has a margin of error of plus or minus 5.8 percentage points.
Wisconsin's primary election is Tuesday and the candidates have crisscrossed the state to rally support.
Bernie Sanders is attracting thousands of people in Wisconsin's liberal capital city for the second time in less than four days.
His campaign stop Wednesday in Madison comes after a new Wisconsin poll showing him in a close race with Democratic rival Hillary Clinton ahead of the state's Tuesday primary.
The Marquette University Law School poll shows Sanders with 49 percent compared to 45 percent for Clinton among likely Democratic voters. The poll of conducted between March 24 and Monday has a 6.3 percentage point margin of error.
As he has across Wisconsin in the past week, Sanders is railing against Republican Gov. Scott Walker and new voting laws that opponents say make it harder for Democrats to cast ballots.
