For weeks the Maine Republican Party has been aggressively attacking — or "vetting" — Angus King, the independent candidate for U.S. Senate.

It wasted little time Friday pouncing on King’s new television ad. Shortly after Republican candidate Charlie Summers’ campaign claimed that King rushed to get the spot on the air to respond to what Summers surrogates have described as a "moderate" ad buy that began in the 2nd Congressional District, the Maine GOP questioned whether the King camp illegally used the GoogleEarth logo in its spot. 

From the party’s release:

"There are some serious questions about (the ad), however. The GoogleEarth logo at the bottom of the screen as the camera zooms in on a map of the earth raises the question of whether the King campaign has permission to use the imagery.    

‘Did the campaign get permission from Google to use their corporate logo, or are they playing fast and loose with the laws and trying to pull a fast one on Mainers?’ asked David Sorensen, spokesman for the Maine GOP. "

Progessive blogger Gerald Weinand asked the same question of the King campaign. Its answer: Yes.

Here’s the contract the King campaign signed with Google:
