Anchorage, Alaska (CNN) - Sen. Lisa Murkowski could concede the GOP Senate primary as early as Tuesday night after election officials in Alaska finish counting the day's absentee ballots.
In an interview with CNN, Murkowski campaign spokesman Steve Wackowski was emphatic that the vote could still swing their way. "We're being hopeful, we want to make sure that all the votes are counted," he said.
But Wackowski also addressed the harsh reality that Murkowski might fall to the once lesser known, Tea Party Express-endorsed Joe Miller.
"I think we should know ... by our calculus, we should know by tonight," Wackowski said.
Wackowski was asked if Murkowski might concede the race to Miller once Tuesday's ballot counting ends. "Unfortunately we've got all our options are on the table," he lamented.
Officials with Alaska's Division of Elections spent Tuesday counting thousands of absentee ballots and looking over others that might present potential challenges. Currently, Miller leads the vote tally by just under 1,300 votes, a lead that has shrunk, slightly, since counting began in the morning.
The Murkowski campaign spokesman also took aim at forces that worked to defeat, what they saw, as a Republican senator who'd become increasingly liberal.
Regarding the Tea Party Express' endorsement of Miller, and its support on Miller's behalf, Wackowski said, "they went very negative, very fast."
The spokesman went on to accuse the group of a mass misinformation campaign about Murkowski in Alaska.
"They kind of disregarded the facts about her record...they would spat out lies and they would spat them out louder and louder and louder," Wackowski told CNN.
As an example, Wackowski said, "There's a legend out there that she opposed the repeal of 'Obamacare.' Completely not true."
And the campaign spokesman said he foresees the Tea Party movement possibly doing long-term damage to the Republican party as it drives to root out so called "RINOS ("Republicans in Name Only") in favor of more committed conservatives.
"They're spending their resources to try to take down a fellow conservative. I wish they would've stayed in California, for instance, and fought Barbara Boxer," Wackowski said.
"We've got Republicans fighting each other here, when I wish they could've unified us and we could have focused on trying to gain a majority in the U.S. Senate."
CNN contacted representatives of the Tea Party Express for reaction but did not receive an immediate response.
