Sen. Jim DeMint (R-S.C.) is asking supporters of his Senate Conservatives Fund to help him build a war chest ahead of the 2012 elections, when Republicans are hopeful they can take back the majority in the Senate.

In an email sent Tuesday with the subject line “Say No to RINOs in 2011,” DeMint pledged that the Senate Conservatives Fund will play a key role in the upcoming legislative battles in the Senate with an eye towards 2012.
