Washington (CNN) – Still swaggering after its recent electoral successes, the Tea Party movement appears to be growing more emboldened as it tries to blaze a path to power.
One new bold move: An activist group is publicly parading a list of lawmakers the group is determined to oust from office.
On Thursday, the Tea Party Express added two more names to its "2012 Tea Party Target List" - Democratic Sen. Debbie Stabenow of Michigan and Republican Sen. Olympia Snowe of Maine.
The language in a press release is emblematic of how Tea Party activists appear to be growing ever more audacious.
"Stabenow has been an advocate for the big government nanny state, forgetting that we the people tell the government what to do, not the other way around," Tea Party Express Chairman Amy Kremer said in the statement. Kremer added, "We think it's only appropriate that the Senate be more fair and balanced by replacing her with a constitutional conservative."
CNN contacted Stabenow's office but did not receive a response.
Tea Party activists have long worked against Democrats. What appears to be growing is a separate tactic: The movement's thumbing its nose at the GOP - the party that most ideologically identifies with the Tea Party.
Activists say moderate Republicans, that they believe are not bona fide fiscal conservatives, should be purged from the party. But some critics essentially accuse the Tea Party of the political equivalent of eating their own.
Case in point: the Express e-mail is especially harsh against Sen. Snowe.
"Olympia Snowe dishonors the notion that the Republican Party is supposed to be the fiscally conservative, constitutionalist political party in America," Kremer states.
The Express recently added Nebraska Democratic Sen. Ben Nelson and Indiana Republican Sen. Richard Lugar to its "Target List." And the group vows to reveal more names later this year.
But conservative activists may be hard-pressed to achieve their goals. Snowe, a moderate Republican, has been re-elected two times since winning the seat in 1994. Also, Maine has gone for a Democrat in every presidential election since 1988. And, despite his critics, Lugar is considered a respected voice on foreign policy and other issues.
Meanwhile, despite helping Republicans take back the House, the Tea Party movement lost three high-profile races that, arguably, it wanted to win the most: Sharron Angle lost to Sen. Majority Leader Harry Reid in Nevada; Christine O'Donnell lost to Democratic Sen. Chris Coons in Delaware; and after a protracted battle in Alaska, the Tea Party-backed Joe Miller fell to Republican Sen. Lisa Murkowski.
In a statement to CNN, Snowe's chief of staff harshly reacted to the charge that the senator is not a true fiscal conservative.
"The idea that Senator Snowe dishonors the notion that Republicans are the fiscally conservative party is absurd," John Richter said. "If they had supported her legislative trigger mechanism back in 2001, to preserve federal surpluses and pay down our debt, and to open a window of opportunity to strengthen Social Security and Medicare, we would not be in this situation today with our national debt.
Richter added: "If they had supported the constitutional balanced budget amendment she championed throughout her tenure, we would not be in this situation today. And if they had supported offsets as Senator Snowe did in 2003 when she thought it was prudent to do so, we would not be in the situation we're in today. So obviously, they are totally unfamiliar with her record on fiscal responsibility."
CNN, the Tea Party Express and other Tea Party groups are hosting a first-ever Tea Party debate for Republican candidates this fall.
