Attorney Joe Miller is still considered a long shot ahead of Tuesday's Republican Senate primary in Alaska, but the Tea Party Express has spent nearly $150,000 running radio and TV ads on his behalf over the past week.
The PAC's latest Federal Election Commission filing shows another $18,915 buy placed Sunday. The group has also spent close to $36,000 on two last-minute mailers that hit mailboxes over the weekend. In all, the Tea Party Express has spent more than $500,000 in the state this year.
Still, Sen. Lisa Murkowski's (R-Alaska) campaign appears confident ahead of Tuesday. Miller's camp claims internal polling has the race within single digits, but a source close to Murkowski's campaign said their internals have the senator well ahead.
Former Alaska Gov. Sarah Palin (R), who endorsed Miller in June, recorded a last-minute robocall for the campaign that went out to voters Monday. She also posted a fundraising appeal on her Facebook page trumpeting Miller's efforts to raise $30,000 for a late TV buy.
"Joe may be the underdog in this fight (because by using the power of a politician’s incumbency after being given her Senate seat by her father, Lisa Murkowski has outspent Joe six to one), but Alaskans see through this and are recognizing Joe’s ability to be a real leader," Palin wrote on her Facebook page.
Palin's political feud with the Murkowskis began in 2006 when she defeated Gov. Frank Murkowski (R) in a Republican primary. Palin has had a rocky relationship with his daughter, Lisa Murkowski, since.
In the robocall she recorded for Miller, Palin also hit Murkowski for voting with Senate Democrats and accuses the senator of "co-sponsoring cap-and-trade."
Despite being wooed by Senate Democrats, Murkowski opposes the current cap-and-trade proposal backed by President Obama. In 2007, Murkowski did co-sponsor a scaled-back version of the bill as part of an attempted bipartisan compromise.
