LAWRENCEBURG, Tenn. (AP) — Tennessee Sen. Bob Corker said Wednesday he isn’t ruling out joining the field of Republicans running for president in 2016, but any decision would wait until next year.If Corker joined the race, he would face fellow Republicans with much higher national profiles. He also hasn’t taken any clear steps to organize, fundraise or make appearances in early primary states — typically the first signs of a potential campaign testing its reception.Corker, too, would have to mend ties with the GOP’s arch-conservatives, who could be uneasy over Corker’s reputation to work alongside Democrats on fiscal issues.“There are times when I do wish I could have the kind of impact and create the kind of change and have the kind of vision for our country that so many people here in Tennessee would like to see happen,” he said during a chamber of commerce appearance in Lawrenceburg, about 70 miles south of Nashville.The senator, who is two years into his second term, said running for president would be a tough sell to his wife, Elizabeth, who has remained in Chattanooga while he has served in Washington and “loves her anonymity.” He said she may be wary of the intense media attention and scrutiny.He cited fatigue from a recent trip to Southeast Asia for what he called “a stream of consciousness” response to whether he would run for president.“I’ll probably be ridiculed when I get into the car,” said Corker, the top Republican on the Foreign Relations Committee.His latest comments appeared to strengthen a hint last month.
