A new Marquette Law School Poll national survey of registered voters finds President Joe Biden trailing against each of the top three potential Republican candidates, with former South Carolina Gov. Nikki Haley leading Biden 55% to 45% among registered voters. Former President Trump leads Biden 52% to 48% in the same category, while Florida Gov. Ron DeSantis holds a 51% to 49% advantage.

Among likely voters, Haley sees her advantage rise to 12 percentage points at 56-44. The Biden-DeSantis hypothetical does not change with likely voters, while Trump’s support decreases to 51% against Biden’s 49%.

These results include initially undecided voters who were then asked to choose one of the candidates.

Among registered Republican voters, Trump maintains a substantial lead over all others in the primary field for the GOP nomination, with 54% of the total. DeSantis and Haley are tied at 12%. That represents a rise for Haley and a decline for DeSantis since March. No other candidate has more than 4% support in the current poll.

The survey was conducted Nov. 2-7, 2023, interviewing 856 registered voters nationwide, with a margin of error of +/-4.5 percentage points. For likely voters, the sample size is 668, with a margin of error of +/-5 percentage points.

The Marquette Law School Poll has seen a close race between Trump and Biden among registered voters since May, with the trend shown in Table 1. Among likely voters in September, Biden received 51% to Trump’s 49%. Likely voters results are not available for earlier polls.
