(CNN) - The tweets are a-flyin' in the last great frontier. Again.
Alaska GOP Senate nominee Joe Miller's campaign has deleted at least four tweets published on its official Twitter account Wednesday night that imply Miller feels his election is all but certain.
"Think I'll do some house hunting while I'm in DC," one of them read.
And then: "Guess I should pick out some office furniture, as well …"
Plus: "Then there's matter of a name plaque for the door."
Miller's campaign spokesman, Randy DeSoto, told CNN on Thursday that "a volunteer was responsible for the tweets last night and will no longer have access to the account."
Miller's Democratic opponent, Scott McAdams, fired back Thursday with a tweet of his own.
"[Joe Miller:] While you're in DC picking out office furniture, I'm in Anchorage introducing my plan to get Alaskans back to work," the tweet read.
A spokesman for Sen. Lisa Murkowski, who lost to Miller in the GOP primary last month and is now running write-in campaign to keep her job, said, "for someone who wants to be a freshman senator, this is pretty sophomoric."
It's not the first time Miller's campaign has blamed a controversial tweet on a low-level staffer.
On August 27 – as the outcome of a GOP primary remained unclear and a recount was pending – Miller's campaign published a tweet that suggested "the oldest profession" was comparable to the possibility that Murkowski might "sell out" the Republican Party to run as third-party candidate.
"[The staffer was] not suggesting in any way that Sen. Murkowski is prostituting herself," DeSoto said at the time. He said the staffer removed the tweet after realizing it was rapidly spreading on Twitter and nearly everyone was interpreting it as an attack on Murkowski.
Murkowski's campaign called it a "smear campaign."
A CNN/Time/Opinion Research Corporation poll released Wednesday shows Miller is statistically tied with Murkowski, holding a 38 to 36 percent point lead. McAdams has the support of 22 percent of likely voters. The poll's margin of error is plus/minus 3 percentage points.
