With the results of Alaska's Republican Senate primary still in doubt, National Republican Senatorial Committee Chairman, Sen. John Cornyn (R-Texas) guaranteed Wednesday that his party would retain the seat in November.

“As we await the final outcome of the Republican primary in Alaska, one thing is clear — this seat will remain in Republican hands this November," Cornyn said in a statement. "While political pundits and the Democrats in Washington will attempt to spin this race inside the Beltway, the fact remains that voters in Alaska and across America are deeply concerned about the reckless spending and rapid growth of government that we’ve witnessed under the Obama White House and the current leadership in Congress."

Attorney Joe Miller appears on the verge of scoring a stunning upset over NRSC-backed Sen. Lisa Murkowski (R). Miller holds a lead of less than 2,000 votes with 97 percent of precincts reporting. Several thousand absentee ballots are left to be counted. 

Should Murkowski lose, she would be the third sitting senator to be defeated in a primary this year. Sens. Arlen Specter (D-Pa.) and Bob Bennett (R-Utah) also lost out on their respective party nominations. 

Murkowski also stands to be the latest NRSC candidate to lose a Republican primary to a Tea Party-backed challenger. It has happened in four other states this primary season — Colorado, Utah, Nevada and Kentucky.
