Sen. Barack Obama’s presidential campaign says it’s continuing to ramp up its Nevada forces.

The campaign says it’s adding three new offices in the early caucus state, bringing its total to 10.

The campaign says Boulder City, Henderson and Winnemucca field offices are slated to open over the next two weeks.

Nevada will host a what could be a hotly contested Democratic nominating contest on Jan. 19, 11 days after the New Hampshire primary.

Obama Campaign Manager David Plouffe says he expects Nevada to be “the center of the political world” during that time.

The Illinois senator’s campaign has been adding resources to the state. It launched its first television ads on Tuesday, the same day rival Sen. Hillary Rodham Clinton ran her first ads.
