MILWAUKEE — A new Marquette University Law School survey found that among registered voters, support for former President Donald Trump is on the rise, with him earning more support than Florida Governor Ron DeSantis.
The university surveyed 1,005 adults across the country from July 7-12. The results have a margin of error of +/- 4 percentage points.
Marquette's survey showed 46% of those polled would choose Trump for the Republican Presidential nomination if the election was held today. DeSantis received 22% of the votes, while other candidates earned the remaining percentage.

If the nomination was just between DeSantis and Trump, Marquette found 54% of the Republicans polled, 54% said they'd vote for Trump while 46% said they'd choose DeSantis. DeSantis had been leading in this poll in previous surveys, but Trump has since overtaken him.
The Marquette University Law School also looked at potential matchups for the 2024 election, including a rematch of 2020 with a Trump vs President Joe Biden election. The university found among likely voters, both Trump and Biden received 50% of the vote.
Marquette said there is strong party-line voting in their results, with little crossover. Among independents, Biden holds a small edge over Trump, Marquette found.

If the race were to come down to DeSantis and Biden, the survey results show DeSantis having a slight edge over Biden, with DeSantis receiving 51% of the votes among registered voters.
Marquette also asked registered voters about abortion, classified documents and Trump's indictment, job approval, and favorability for both parties. You can view the full survey results here.
