Insiders' Pick as McCain Running Mate: Portman

Ex-Congressman and ex-OMB director Rob Portman has much to offer John McCain as a running mate, writes Washington Post blogger Chris Cillizza. "If Washington-based political operatives picked the vice president, Portman would have it hands down" because he's "that rare breed of politician who is equally conversant—and skilled—at policy and politics."

Choosing Portman would appease party insiders and help the GOP in Ohio, Portman's home state. The economic expert is also a debate pro, having played the part of Joe Lieberman and John Edwards in mock sessions with Dick Cheney. One proponent praises him for being “able to convey technical policy concept in a user-friendly way.” (More John McCain stories.)
