The republican candidate for western Iowa’s Congressional seat supports dumping the federal income tax, and instituting a national sales tax.Steve King, who runs an earth-moving company in Kiron, says it may not be politically possible to enact a national sales tax, so he would favor a “flat” income tax as an alternative. King also says if elected, he’ll push a bill that’d make English the nation’s official language. He says it’s something he’s believed in since eighth grade. He says every other country has a single language, and it bonds people together.Republican President Bush has rebuked the idea, saying it sends an unwelcoming message to Hispanics and other, new Americans. King says he will defy Bush on the issue.King says the President doesn’t have “ultimate wisdom” on every issue. King was a backer of the new state law which declares English Iowa’s official language. King made his comments on Iowa Public Television. King will face democrat Paul Shomshor in the November election.
