Jan 26 03:56 AM US/Eastern LAS VEGAS (AP) - President Barack Obama is returning to two states that are important to his re-election, Nevada and Colorado, promoting his energy agenda while grabbing some of the political spotlight ahead of his Republican adversaries. Obama will speak at a UPS center in Las Vegas and at Buckley Air force Base in Aurora, Col., Thursday, drawing attention to proposals for clean energy and greater domestic oil and gas production. The pitch comes just days after he drew Republican criticism for rejecting a cross-country oil pipeline from Canada. Obama visited both states in late October, using that trip to launch a phase of his campaign to jumpstart the economy. With economic indicators improving, Obama now visits on a higher note. Both states hold their Republican presidential caucuses within the next two weeks.
