Sen. Lisa Murkowski (R-Alaska) on Wednesday released two new TV ads her campaign says will counter the Tea Party Express.

Earlier this week, the group unveiled its own TV ad targeting Murkowski, which spokesman Levi Russell said he hopes will be on the air in Alaska within the next two weeks. Russell said the spot will send a clear signal to Murkowski, "We voted you out once, and we'll do it again."

Murkowski is waging a write-in bid this fall against Republican Joe Miller, who defeated her in the primary, and Sitka Mayor Scott McAdams (D). One of the new spots shows voters how to write-in and spell Murkowski's name.

The second ad targets the Sacramento-based Tea Party Express directly.
