(CNN) - Sarah Palin appears to be picking up the pace when it comes to 2014 endorsements, backing conservatives in Oklahoma, Nebraska, and Mississippi for the U.S. Senate.
Thursday the former Alaska governor and 2008 Republican vice presidential nominee backed Chris McDaniel, the conservative state senator in MIssissippi who's primary challenging six-term U.S. Sen. Thad Cochran.

"Chris McDaniel has a proven record of fighting for conservative principles in the Mississippi State Senate," wrote Palin on her Facebook page.
"The Mississippi Senate race is a clear fight for the future of the Republican Party against the entrenched interests of the permanent political class in D.C. We desperately need new conservative leaders in the U.S. Senate who will serve with passion, intelligence, and integrity," Palin added.
Earlier Thursday Palin endorsed Ben Sasse for the GOP nomination in Nebraska. The Midland University president is running to succeed retiring Republican Sen. Mike Johanns
"Ben knows how dysfunctional D.C. is. He's witnessed firsthand the corrosive effect bad big government policies can have, and he knows that Obamacare is as bad as it gets," Palin wrote on her Facebook page.
Sasse also has the backing of Senate Conservatives Fund and Club for Growth, two D.C.-based groups that endorse and support conservative candidates. But another candidate in the race for the GOP nomination, former Treasurer Shane Osborn, is backed by FreedomWorks, a national group that carries a lot of clout among tea party activists.
Wednesday afternoon, Palin endorsed former Oklahoma House Speaker T.W. Shannon in his bid for the open Senate seat in his state. Shannon is battling Rep. James Lankford and a number of other Republican candidates for the GOP nomination, in the race to succeed retiring Republican Sen. Tom Coburn, who is stepping down at the end of the year.
"Tom Coburn leaves large conservative shoes to fill as he retires from the U.S. Senate. At 6'5 feet tall, T.W. Shannon is just the leader to fill them," wrote Palin on her Facebook page of Shannon, who was the first African American to serve as Oklahoma House speaker and is considered by many on the right as a rising conservative star.
While major D.C. based groups on the right are not supporting Lankford because they feel he's not conservative enough, they are not backing Shannon at this time.
The Senate seats in all three states are expected to stay in GOP hands in November's midterm elections.
Earlier Wednesday, Palin wrote that she would shortly announce a series of endorsements.
Earlier this year Palin backed tea party activist Katrina Pierson, who launched a primary challenge against longtime GOP Rep. Pete Sessions of Texas. Session, the House Rules Committee chairman, easily defeated Pierson. Palin also endorsed Texas Attorney General Greg Abbott for the Lone Star State's Republican gubernatorial nomination. Abbott, facing no seriously party opposition, won the nomination in a landslide.
Palin, who is still very popular and influential with many tea party activists and other conservatives, weighed in on dozens of Republican primary races in the 2010 cycle, but she cut back the number of her endorsements in the 2012 elections.
