SPRINGFIELD, Mo. (AP) - Democratic U.S. Senator Claire McCaskill is hoping a little good fortune can rub off from Republican Senator Roy Blunt. McCaskill's campaign has leased the same recreational vehicle used by Blunt during his successful 2010 bid for the U.S. Senate. When Blunt used the RV, it was emblazoned with the slogan: "Jobs for Missouri's future." McCaskill has covered the RV with the slogan: "A senator on our side."
