(CNN) - The Senate Republican primary race in Alaska still isn't over, but Democrats are moving fast to define Joe Miller - the previously unknown attorney who is on the verge of upsetting incumbent Sen. Lisa Murkowski.
In a statement Wednesday, DSCC Communications Director Eric Schultz described Miller as "an extremist who intends to transition-out Social Security, phase-out Medicare, and end unemployment benefits for all Alaskan families."
"Joe Miller seems more intent on imposing a strict social doctrine to please his out-of-state tea party backers but would leave the people of his state high and dry. Alaskans deserve a Senator who will stick up for them in the United States Senate," Schultz added.
The Anchorage Daily News reported last month that Miller has called for phasing out government Medicare and Social Security, as well as nixing the federal Department of Education.
"The only answer [to cut spending] is to return our federal government to the limits prescribed by our Constitution," Miller says on his Web site. "Federal powers not specified in the Constitution are reserved to the States by the 10th Amendment."
Miller, a graduate of West Point and Yale Law School, holds a slim lead over Murkowski with about 15,000 absentee ballots yet to be counted. Miller benefitted highly from the support of the Tea Party Express and former Alaska Gov. Sarah Palin.
