Nearly three-fifths of Republicans said they trust Donald Trump more than House Speaker Paul Ryan to lead their party, according to a new poll released Tuesday.

When NBC News/Survey Monkey pollsters asked GOP voters, “Who do you trust more to lead the Republican Party?,” 58 percent of respondents said Trump and 39 percent favored Ryan.

Ryan, the nation’s highest-ranking elected Republican, has been slow to endorse the likely GOP presidential nominee.

Republicans who call themselves “very conservative” pick Trump over Ryan, 63 percent to 34 percent.

But among “moderate” GOP voters, Trump’s margin of support over Ryan drops to 57 percent to 40 percent.

With Trump storming to the GOP nod and Hillary Clinton moving closer to the Democratic nomination, their potential November confrontation is already shaping up to be a very competitive race.

The NBC poll — taken between May 9 and Sunday — showed Clinton leading Trump, 48 percent to 45 percent. That’s down from a 48-45 Clinton lead when the poll was taken between May 2 and 8.

Clinton hasn’t been able to shake off challenger Sen. Bernie Sanders (D-Vt.), who insists his populist campaign is the best suited to take on Trump in November — and this polling seems to back him up.

While Clinton leads Trump by just 3 points, Sanders leads the Manhattan real estate developer by a margin of 53 percent to 41 percent in a hypothetical matchup, Survey Monkey found.

But the former socialist mayor of Burlington, Vermont, still trails Clinton among national Democrats, 54 percent to 40 percent.

This poll’s margin of error is plus or minus 1.2 percentage points for the total sample and 2.0 percentage points for the Democratic survey.
