(CNN) - Election Day arrived for Nevada residents Saturday as early voting began with the state's Senate campaigns jockeying for votes.
Democratic incumbent Sen. Harry Reid and Republican challenger Sharron Angle are looking at early voting as a key barometer for how they're doing now, and how they will do in the November election.
Fifty-eight percent of Nevada ballots cast in 2008 came from early voting, and the campaigns expect 40 percent to 50 percent of the vote this year will come from early voting.
The Reid campaign has concentrated a significant amount of resources in getting out the vote and has focused its efforts on the Latino community in particular. Reid is attending three events Saturday to encourage early voting.
"For the last four years, we have been building a state-of-the-art get-out-the-vote operation geared toward getting our voters to the polls during the final two weeks of this election," Jon Summers, a Reid campaign spokesman, said in a statement.
Angle's campaign is hoping its enthusiasm will help equal the Democratic efforts in the state.
"Sharron is famous for her grassroots get-out-the-vote operation," Jarrod Agen, Angle's communications director said in a statement. "She will personally be precinct walking and knocking on doors throughout early voting to get people to the polls."
Both camps will be helped by high-profile visits in the coming week. President Barack Obama will visit Nevada on Wednesday, and on Monday former Alaska Gov. Sarah Palin and Republican National Committee Chairman Michael Steele will visit the state as part of their Tea Party Express tour.
According to recent polls, the Nevada Senate race remains deadlocked.
