With seven of the most-named running mates listed to speak at the Republican National Convention, the veepstakes over John McCain's vice presidential running mate is anyone's guess.

The convention line-up, which will be held in St. Paul, Minn., from Sept. 1-4, features Connecticut Independent Democratic Sen. Joe Lieberman on the first night; former Pennsylvania Gov. Tom Ridge and Alaska Gov. Sara Palin on the scond night; former Massachusetts Gov. Mitt Romney and Louisiana Gov. Bobby Jindal on the third night; and Minnesota Gov. Tim Pawlenty and Florida Gov. Charlie Crist on the last night.

The third night is the night the vice presidential nominee will give his acceptance speech. Other speakers that night include Cindy McCain, former eBay CEO Meg Whitman and former Hewlett-Packard CEO Carly Fiorina.

Jindal has said he is not interested in the job but Romney has clearly indicated he would accept the nod. FOX News learned this week that Ridge is no longer under consideration because of his support for abortion rights.

McCain is expected to announce his choice for running mate at a rally in Dayton, Ohio, on Aug. 29. The date is  his 72nd birthday and the day after the Democratic National Convention ends.

Also in the line-up of speakers at the GOP convention are President Bush and first lady Laura Bush, Vice President Dick Cheney and California Gov. Arnold Schwarzenegger as well as former presidential rivals Mike Huckabee, Rudy Guiliani and Fred Thompson.

Most notably absent from the list of headline speakers is South Carolina Gov. Mark Sanford, who also has been listed as a potential vice presidential candidate.
