(CBS News) Now that Mitt Romney appears to be on his way to winning the Republican presidential nomination, he's finally thinking about a potential running mate.
Romney has named his trusted, longtime adviser Beth Myers to head up the search for his vice presidential pick, the candidate told ABC News.
"I have selected someone who has been a counselor of mine for a number of years, Beth Myers. She was my chief of staff when I was governor," Romney said in an interview with ABC's Diane Sawyer that will air Monday night. "I've asked her to be the person who oversees the process of the vice presidential selection and vetting an analysis and so she's begun that process and is putting together the kinds of things you need to do to vet potential candidates."
Myers was Romney's chief of staff during much of his tenure as Massachusetts governor and headed his 2008 presidential campaign.
A vice presidential choice is a tactical one -- the right pick can help a presidential candidate shore up a policy weakness or add some geographic balance to the ticket. The choice also serves as a test of the nominee's decision making ability and a window into his thought process. CBS News has compiled an early list of some of Romney's possible choices .
