(CNN) - They served on the same Republican presidential ticket in 2008, but they're divided over who to support in the 2012 Indiana Senate race.
Sen. John McCain, the 2008 Republican presidential nominee and his former vice presidential running mate former Gov. Sarah Palin picked their candidates in the state's Republican primary on Friday with McCain backing fellow incumbent Sen. Richard Lugar and Palin supporting Lugar challenger and State Treasurer Richard Mourdock.

McCain, the senior Arizona senator, recorded a radio ad for Lugar, set to run in the state on Friday, in which he highlights the six-term incumbent's opposition to "Obamacare" and efforts to keep the United States safe. Lugar is the ranking Republican on the Senate Committee on Foreign Relations.
"Some in Indiana are claiming Dick Lugar is Obama's friend. That's ridiculous, and I know firsthand because I fight alongside him every day in the Senate," McCain said in the spot. "Dick Lugar is a patriot and a hero, and we need him in the United States Senate."
Palin announced her support of Mourdock in a Facebook post. She said Lugar's service is "appreciated," but "it's time for the torch to pass to conservative leadership in Washington."
"Indiana deserves a conservative in the Senate who will fight for the Hoosier State, uphold our Constitution, and not just go along to get along with the vested interests of the permanent political class in D.C.," Palin wrote.
"Our response to Palin is that we have a new ad out today from Gov. Daniels and the ad from Sen. McCain," Lugar spokesman Andy Fisher told CNN.
Republican Gov. Mitch Daniels of Indiana released his second television spot in support of Lugar on Friday.
Lugar and Mourdock are set to face off in the Republican primary on May 8, the first significant primary challenge Lugar has sustained since he entered the Senate in 1976.
Mourdock, who has criticized Lugar's past work with Democrats, enters the final phase of the campaign with backing from major conservative groups, while Lugar has painted himself as a consistently conservative fighter on behalf of Hoosier voters.
Even Vitetnam didnt wat McCain GO MOURDOCK
Who does "Joe the Plummer" endores? Another Tea Party idiot
They deserve each other.
If you wanna win an election, get McCain off your endorsement list. McCain is really a closet liberal and should be on the Dems side of the aisle.

Dumb and Dumbest!
Is Palin in the news again??? she is so irrelevant and needs to go back to Alaska... who cares what she thinks?? her 15 minutes of fame should be over..
I LOVE it when they quarrell among themselves . . .
Palin has to show her rebellious side always. She is mentally off and has a tendency to back losers. She wanted Gingrich which shows her mental state. Dumb. She is a wannabe, but can never be.
i dont see how pains endorsement could help anyone.... but the president.
Pathetic and sad. One politician bashing another because of the crime of being bipartisan. No matter who is in control Congress is going nowhere. Absolutely toxic.
Who cares with Sarah Palin says,she should have ran for a public ,if she has all the solutions.Instead,she hides to avoid debating and explain her idealogy
Perfect for the rednecks in Indiana.
I think it is genius movement. Whether they wanted the focus to be McCain-Palin or whther people like what they have to say.It brings focus to this race where we have not heard that much about it.Both candidates will get endorsements one way or the other because of the publicity this story brings.Truely, what my opinion, their opinion, it doesn't matter.People should get the facts and vote their own way.That is the beauty of this country. ~GOP 4VR~
