Congressman Matt Santos (D-TX) (Jimmy Smits) is nominated on the fourth ballot at the Democratic National Convention, during the sixth season finale. Santos was planning to leave Congress before being recruited to run for the presidency by Josh Lyman. Santos polled in the low single digits in the Iowa caucus and was virtually out of the running in the New Hampshire primary before a last-ditch direct television appeal vaults him to a third-place finish with 19% of the vote. Josh Lyman, Santos's campaign manager, convinces Leo McGarry to become Santos' running mate.
