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 e-mail 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. RINO stands for politicians who are seen by some as "Republican in name only" and lack certain conservative credentials.

In the fundraising appeal, DeMint also reminded supporters that five of his political action committee's endorsed candidates won this past November. He highlighted victories by Sens.-elect Pat Toomey (Pa.), Marco RubioMarco Antonio RubioIf we seek resilience, we need liberty, not nationalism GOP senator blocks bill giving flexibility to small-business loans but says deal near GOP senators dodge on treatment of White House protesters MORE (Fla.), Rand PaulRandal (Rand) Howard PaulPaul clashes with Booker, Harris over anti-lynching bill Rand Paul holding up quick passage of anti-lynching bill Democratic senator to offer amendment halting 'military weaponry' given to police MORE (Ky.), Mike LeeMichael (Mike) Shumway LeeHillicon Valley: Facebook employees speak up against content decisions | Trump's social media executive order on weak legal ground | Order divides conservatives The Hill's Morning Report - Presented by Facebook - Trump tweets as tensions escalate across US GOP deeply divided over Trump's social media crackdown MORE (Utah) and Ron JohnsonRonald (Ron) Harold JohnsonGraham postpones Russia probe subpoena vote as tensions boil over GOP votes to give chairman authority to subpoena Obama officials Democratic senator to skip vote on Obama-era subpoenas MORE (Wis.). 

"I believe we can build on these victories over the two years and elect several more conservative standouts to the Senate in 2012," DeMint wrote. 

Republican Senate hopefuls are already courting DeMint, whose PAC funneled millions to GOP candidates during the 2010 cycle and offered critical endorsements in a number of Republican primaries.
