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 RubioSenate Republicans eye rules change to speed Trump nominees Overnight Defense: Trump unveils new missile defense plan | Dems express alarm | Shutdown hits Day 27 | Trump cancels Pelosi foreign trip | Senators offer bill to prevent NATO withdrawal Bipartisan senators reintroduce bill to prevent Trump from withdrawing from NATO MORE (Fla.), Rand PaulRandal (Rand) Howard PaulHouse Republicans call for moving State of the Union to Senate chamber GOP rep: 'Rand Paul is giving the president bad advice' on Afghanistan and Syria Rand Paul suggests holding State of the Union in Senate MORE (Ky.), Mike LeeMichael (Mike) Shumway LeeHillicon Valley: Trump AG pick signals new scrutiny on tech giants | Wireless providers in new privacy storm | SEC brings charges in agency hack | Facebook to invest 0M in local news AG pick Barr wants closer scrutiny of Silicon Valley 'behemoths' Grassroots political participation is under attack in Utah and GOP is fighting back MORE (Utah) and Ron JohnsonRonald (Ron) Harold JohnsonCongress sends bill renewing anti-terrorism program to Trump The Hill's Morning Report — Shutdown fallout — economic distress Hillicon Valley: Republicans demand answers from mobile carriers on data practices | Top carriers to stop selling location data | DOJ probing Huawei | T-Mobile execs stayed at Trump hotel as merger awaited approval 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.
