A new NBC News/SurveyMonkey online tracking poll released Tuesday found Trump leading the Texas senator, 48 percent to 27 percent. Ohio Gov. John Kasich, who gained 2 points since last week, follows with 18 percent.

When it comes to the possibility of a contested convention, the survey found that a majority of registered Republicans and those who lean Republican, 57 percent, believe that Trump should win the nomination if he wins a plurality of delegates, even if he fails to capture a majority of delegates.

The survey also shows 52 percent of those same voters are happy with a general election match-up between Trump and Democratic presidential front-runner Hillary ClintonHillary Diane Rodham ClintonHillary Clinton slams Trump rally: 'The time has come again' to fight for democracy Trump blasts minority Democrats, rally crowd chants 'send her back' The Memo: Democrats debate Trump response – 'Being righteous and losing sucks' MORE, while 30 percent would consider a third party candidate.

The poll was conducted online March 21–27 and surveyed 6,521 adults, including 5,741 who say they’re registered voters.
