Earlier this year, I wrote “Senator Tea Party,” a story for NR on Jim DeMint’s efforts to support conservatives in GOP primaries. The results of his efforts are now becoming clear, according to CQ:

Sen. Jim DeMint ran up a successful record with the candidates he endorsed in Republican primaries. …
With the victory this week of Weld County District Attorney Ken Buck in the Colorado GOP Senate primary, DeMint added to what has turned out to be a string of victories. DeMint’s overall endorsement record this cycle is six wins and two losses, and two more victories appear forthcoming, with Dino Rossi poised to win the GOP primary in Washington state and Ron Johnson set to win in Wisconsin.
The Senator’s PAC faltered only in California, where state Assemblyman Chuck DeVore never gained traction; and in Indiana, where state Sen. Marlin Stutzman failed to compete.
In Colorado, DeMint backed Buck, who began the race as the underdog, over former Lt. Gov. Jane Norton, the establishment favorite — a strategy he followed in some cases, though not all.
In Washington and Wisconsin, DeMint and the establishment see eye to eye. Both Rossi and Johnson are considered frontrunners, and Rossi in particular was heavily recruited by national Republicans to challenge Senate Democratic Conference Secretary Patty Murray.
However, DeMint also endorsed Sharron Angle, now the GOP nominee in the race against Senate Majority Leader Harry Reid (D-Nev.), when she was just an afterthought in Nevada’s Republican primary.
He also backed Pennsylvania’s Pat Toomey and Florida’s Marco Rubio early, long before the GOP establishment jumped on board their candidacies. SCF-backed candidates also include Rand Paul in Kentucky, although DeMint stayed out of his primary until late in the game; and Mike Lee in Utah, who received DeMint’s endorsement only after Sen. Bob Bennett failed to secure a spot on the GOP primary ballot.
