Des Moines, Iowa (CNN) – Newt Gingrich will hit GOP presidential rival Mitt Romney as a "timid Massachusetts moderate" in a New Hampshire newspaper ad on Wednesday.
The full-page ad, set to run in the influential Union Leader, comes less than one week before the state's first-in-the-nation primary on Jan. 10.

The Gingrich campaign intends to release television ads in the same vein this week. On Tuesday, Gingrich also said he will run ads in the early primary voting states of South Carolina and Florida, which hold their contests later this month.
Calling himself a "bold Ronald Reagan conservative," Gingrich compared his campaign with Romney's on a number of issues in the newspaper ad. Among other claims, Gingrich argued that Romney raised taxes and expanded abortion services as governor.
Meanwhile, Gingrich highlighted his own 98.6% pro-life rating from the National Right to Life Committee and his efforts fighting tax hikes in the House of Representatives.
The ad also reminds readers that the Union Leader's editorial board endorsed Gingrich, a nod that came in late November when Gingrich had surged to the top of several polls.
Gingrich has signaled for days he intends to shift from what he's called an "experiment"–releasing only positive-message advertisements–to a new strategy of releasing ads that draw a sharper contrast to Romney.
But Gingrich staunchly defended his approach as a positive one, arguing that as long as his claims are factual, then they don't qualify as attacks.
"It can't be seen as a negative campaign to describe accurately somebody's record," Gingrich said Tuesday in Burlington, Iowa. "Otherwise why would you have a campaign?"
The former speaker spent the last week railing Romney for abdicating responsibility of the millions spent by a super PAC supportive of the former Massachusetts governor on attack ads against Gingrich.
Gingrich even characterized Romney as a liar on Tuesday.
Meanwhile, Winning Our Future, run by former Gingrich campaign aide Rick Tyler, intends to continue bolstering the former speaker's campaign efforts like they did in Iowa.
The super PAC is legally not allowed to coordinate with the campaign, but Tyler told CNN that, based on Gingrich's public pronouncements, they too will be pivoting to Romney.
"We are currently planning the next phase of our messaging given our new expanded parameters. [Gingrich] is by far the best strategist we have so we listen to him–through the media," Tyler said.
Tyler said they are not announcing any ads yet. The PAC will be "active" in New Hampshire but will focus its resources on South Carolina.
