Sen. John McCain (R-Ariz.) weighed in on the competition on ABC's "Dancing with the Stars" Monday night after contestant Kurt Warner appealed to the senator to tweet his hotline number for the show

"1 Cards fan 2 another..Vote 4 me 2nite!" Warner tweeted at McCain.

The former NFL quarterback and Phoenix resident included instructions on how to vote and added "Pls RT!," prompting McCain to later tweet "Vote for @kurt13warner!!"

Warner and partner Anna Trebunskaya earned a standing ovation for their foxtrot and a score of 23.

The endorsement is particularly noteworthy given Warner's competition on the show: Bristol Palin, the daughter of McCain's 2008 presidential running mate, Sarah Palin, is also competing for the title.
