Corrected: This post has been updated to reflect the size of Romney's initial ad buy on WMUR last week.
Mitt Romney's campaign is preparing to launch its second major advertising flight in New Hampshire, six weeks before the state's first-in-the-nation primary.
The campaign has purchased $85,535 in advertisements on WMUR, New Hampshire's main broadcast station, for ads that will run December 1 to December 6, a Republican source who watches the ad market tells us.
Romney launched a $134,000 buy last week taking President Obama to task just as Obama traveled to the Granite State. A significant buy in the state is $100,000 to $150,000, including cable and other outlets, so $85,000 on a single station is going to be noticed.
Rick Perry is the only other candidate to have advertised heavily in New Hampshire.
We've reached out to Romney's campaign to get details on the new ad. We'll post when we see it.
