Some See Edwards Angling for VP

RALEIGH — Two weeks before the Iowa presidential caucuses, Sen. John Edwards still shows remarkable restraint, compared to his fellow Democratic candidates, in remarks about former Gov. Howard Dean, the front-runner in most polls. In a debate Sunday night in Iowa, Edwards went relatively easy on Dean, and even received an apology from him. Many political observers think that Edwards may be resigned to Dean winning the nomination, and that Edwards is pursuing the party’s vice presidential nomination.
