WASHINGTON (AP) — President Barack Obama is unveiling a plan to boost tourism to the U.S. by making it easier for people in China, Brazil and elsewhere to come to this country, promoting visits to national parks, and adding business executives to a tourism advisory board.The president was announcing those steps and others in a visit Thursday to Walt Disney World near Orlando, just as Republican presidential candidates prepare to blanket Florida ahead of the state's Jan. 31 primary.The White House says that more than 1 million U.S. jobs could be created over the next decade, according to industry projections, if the U.S. increases its share of the international travel market.Thursday's trip is Obama's latest attempt to steal a share of the spotlight from Republicans in the midst of their presidential nomination fight.
