When it comes to the house, where Nevada has two wide-open races without an incumbent, FiveThirtyEight forecasts a 21 seat advantage for Democrats.
"Right now predictions are the Democrats will probably take control of the house, but it going to be a probably remarkably narrow situation," Carlton said.
But with all three congressional races, in the Silver State drawing the attention and donations of national political players, Carlton says how the purple state swings could be a sign for the rest of the country.
"I think Nevada acts as a barometer for the national political climate," Carlton said. "If Nevada goes Republican in those swing districts and the state then that is going to be an indicator that Republicans have done pretty well around the country."
