Insiders are expecting Mitt Romney to go with a conventional choice for his running mate. Picking a new and exciting candidate, like Republican Governors Bobby Jindal of Louisiana or Susan Martinez of New Mexico, runs the danger of having an unvetted candidate make a blunder, which calls Romney's judgment into question. Unlike John McCain, Romney was never a daredevil fighter pilot. He always tries to minimize risk. For this reason, former Minnesota governor Tim Pawlenty and Ohio Senator Rob Portman are the most likely picks. They are solid Republican Midwesterners who are unlikely to embarrass Romney.
