Republican Sen. Lindsey Graham said it's "definitely not a Republican wave" on Tuesday evening.
"It's not a wave for sure, but I think it'll be a very good night," he said.
"If you run that far behind your governor candidate, you probably made a mistake," Graham said of Bolduc, referring to the state's Republican Gov.
"Hats off to the Democrats, they performed well in a lot of these swing districts," Graham said.
"It's not a wave, for sure, but I think it'll be a very good night," he added.
