More Republicans than Democrats have cast ballots since early voting got under way Monday in Colorado, a state with one of this cycle's tightest Senate contests.
Numbers released late Wednesday from the Colorado secretary of state's office revealed that 81,545 Republicans have cast an early ballot, compared to 71,325 Democrats. More than 41,000 unaffiliated voters have already weighed in, according to the data.
So far, Republican early voters outweigh Democrats in all but two of the state's counties: Boulder and Denver.
It's much the same story in Nevada, where the early vote totals are likely already worrying Democrats. According to data compiled by George Mason University's Michael McDonald, Democrats are underperforming with early voters in crucial Democratic terrain.
In Clarke County, which houses Las Vegas, 46 percent of those who have already voted early are Democrats, compared to 38 percent who are Republicans. In the 2008 election, McDonald's totals show that Democrats made up 52 percent of the early vote in the county, to just 30 percent of early votes cast by Republicans.

Both campaigns are pouring resources into early voting, which elections officials in Colorado anticipate could account for more than a quarter of all votes cast in November's midterm elections.

Markey is trailing Gardner by just three points, according to numbers from The Hill Midterm Election Poll. The Republican leads 44 percent to 41, with 14 percent of likely voters undecided.
It's a bit of a different story in North Carolina, though. McDonald's breakdown of the early vote numbers there shows Democrats actually outpacing Republicans, 44 percent to 38. Another 17 percent of voters who have already cast ballots are unaffiliated.
In that state, some Democrats have been trying to make the case that Sen.

He faces Democrat Elaine Marshall, who has crept a bit closer to the incumbent in polls, but still trails.
The latest numbers from Public Policy had Marshall within eight points of Burr, but that is the only public poll of late to show Burr with anything less than a double-digit lead.
