Ramaswamy claimed the support of 10% of likely voters in an Echelon Insights poll conducted June 26-29. DeSantis, meanwhile, claimed 16% support to former President Donald Trump's 49%.
The figures marked a 2% surge for Ramaswamy and a 3% drop for DeSantis since May.
No other candidate earned double digit support. Notably, Ramaswamy still appears to have room to grow as 38% of poll respondents indicated they never heard of him. Only 1% said so for Trump compared to 7% for DeSantis. The survey has a +/- 3.9% margin of error.
