Secretary of the State Denise Merrill said 82,847 registered Republicans, or 21 percent of the 398,437 registered Republicans, voted last week.
The turnout is lower than Republican primaries in 2012 and 2010 when around 28 percent and 30 percent of the party voted, respectively.
“Compared to general elections, primaries consistently have a lower turnout, so exceeding 20 percent was actually a little higher than we originally thought,” Merrill said.
