(CNN) – Amid polls showing a neck-and-neck Senate race in Alaska, Sarah Palin offered a hearty endorsement of Republican nominee Joe Miller Thursday night and called incumbent Sen. Lisa Murkowski's actions "shameful."
"Let's call her the candidate for the entitlement party," Palin proclaimed of Murkowski at the evening rally with Miller at her side. "She can't really find a party. Not independent, not Republican."
Palin's endorsement of the once little-known Miller is credited with helping fuel his surprise victory over Murkowski in the August primary with 51 percent of the vote. Murkowski conceded her party's nomination, but later launched a general election write-in candidacy.
There has long been no love lost between Palin and Murkowski, a fact that was on clear display Thursday as the former Alaska governor took aim at the incumbent senator's campaign tactics.
"The opponent would rather waste the voters time by throwing this mud at Joe!" said Palin, visibly appearing angry. "And this campaign that is throwing this mud is being run by a lot of beltway lobbyists."
Palin also sharply criticized Murkowski's actions in the latest debate between the candidates.
"I find it shameful ... this establishment party politician, shamefully used Joe Miller's honorable military service as a means to attack him," said Palin.
During the contentious debate earlier this week, Murkowski asked Miller, "What would your instructors, what would your classmates at West Point say about how well you have lived up to your code of honor?"
But at the rally Thursday night, Palin indicted the "lame-stream media" for not fully conveying Miller's record of military service.
"I read his resumé, I read his accomplishments, I read his passion for America and I think, 'Are we even fit to tie his combat boots?'" she asked.
You are not getting the truth from the left, and you are not getting the truth from the lame-stream media about the real Joe Miller," she added, noting Miller served in the Gulf War and was awarded a Bronze Star.
A recent CNN/Opinion Research Corporation poll shows a deadlocked race between Murkowski and Miller among likely voters at 37 percent. Sitka Mayor Scott McAdams, the Democrats' nominee trails with 28 percent.
