As voters across New Hampshire lined up to vote in the Democratic primaries Tuesday, the state's Republican Gov. Chris Sununu said on Boston Public Radio that the vote would not be a repeat of the chaos seen after the Iowa Caucuses.

"I'm an engineer, we never use the word 'perfect,'" Sununu said. "But we will get it 100% right.

"It is 100 years of responsibility, of getting it right," he continued. "Because we know that we're that first step the rest of the country looks to."

He also said that while 10 percent is considered high turnout for the Iowa Caucus, turnout in the Granite State will dwarf that.

"We are going to have 50 percent to 60 percent participation tonight and that is phenomenal for a primary," he added.
