Sen. John Kerry will pick North Carolina Senator John Edwards today to be his vice presidential running mate. Kerry and Edwards both ran against each other earlier this year for the party’s nomination.  Edwards is a first-term Senator who worked as trial lawyer before seeking office.  Kerry is expected to make the official announcement in an email to supporters. Later he will appear at a rally in Pittsburg. The New York Post however announced in a front-page exclusive today that Kerry had picked Congressman Richard Gephardt to be his running mate.
