DENVER — Republicans are slashing their television advertising at Colorado's three biggest television stations, a troubling sign for presidential nominee John McCain.
McCain is headed to Colorado Friday, but public records provided by three Denver stations show the GOP this week cut their ad spending for McCain by 46 percent.
National Republicans have also canceled $600,000 worth of television ads for Rep. Marilyn Musgrave, a conservative three-term incumbent in northern and eastern Colorado locked in a tough re-election challenge.
Democratic nominee Barack Obama heads to Colorado in coming days, and vice presidential candidates Sarah Palin and Joe Biden headlined Colorado rallies this week.
