Boston (CNN) - Newt Gingrich is back to tangling with the Clintons.
In an interview with CNN, the former House speaker and presidential candidate accused Hillary Clinton of planning to pursue "left-wing ideas" in a series of upcoming speeches that may be setting the stage for her own White House run in 2016.
The former secretary of state announced her foray back into discussing the nation's pressing political issues at an address to the American Bar Association last Monday, a speech she used to sharply criticized voter ID laws recently passed by conservative governors.
"Anyone who says that racial discrimination is no longer a problem in American elections must not be paying attention," Clinton told the audience.
Clinton said she would continue to comment on a range of topics. Her next speech will cover "transparency" in national security polices at an event in Philadelphia next month.
Asked whether Republicans could defeat Clinton in 2016, Gingrich launched into an attack on the former secretary's upcoming speeches.
"First of all Hillary Clinton may beat Hillary Clinton," Gingrich told CNN Wednesday afternoon at a Republican National Committee summer strategy session in Boston.
"If she runs around the country and adopts a series of left-wing ideas in order to preempt the primaries, she may isolate herself so much from the average American that she defeats herself," he added.
A Clinton spokesperson did not respond to a request for comment on Gingrich's remarks.
Gingrich, who will soon debut as a co-host of CNN's "Crossfire," grabbed the GOP's attention earlier Wednesday when he accused the party of having "zero" ideas for replacing the nation's new health care law.
The former speaker said his comments were aimed at getting the party and its consultants out of "the habit of attacking, attacking, attacking."
"In the long run that doesn't get you to govern," Gingrich told CNN. "To govern, people have to decide that they want your ideas, your solutions."
As for Clinton, Gingrich said he once saw the former Secretary as "unbeatable" in 2008. Her upcoming speeches, Gingrich added, has changed that assessment.
"I'm not going to come out and say she's unbeatable this time. Because in fact I think we have clear proof that secretary, Senator Clinton is quite capable of losing if she stays in the field long enough," Gingrich said.
