Shortcomings in Republican efforts during the elections are a reason Michael Steele should not continue as chairman of the Republican National Committee (RNC), a senator said in an interview Sunday.

"Our ground game was not as strong as it could've been. We were outmanned on the ground," Sen. Jim DeMint (R-S.C.) said on Fox New Sunday.

DeMint said Steele should be ousted because Republicans could have done a better job reaching voters.

Noting that he appreciated Steele's service, DeMint joined a current of criticism for GOP fundraising and get-out-the-vote efforts after the elections. These assessments have dogged the RNC chairman despite Republican gains.

"We need a strong national Republican organization to help organize the Tea Parties and other citizen action organizations," DeMint said, referring to the 2012 elections.

Democrats outmatched Republicans during the midterms in terms of "boots on the ground," DeMint said.  

As for whether he might be at the top of the ballot in 2012, DeMint said he has "no plans to run for president."
