Americans are getting more negative about the Tea Party with nearly 50% saying in a new poll that they have an unfavorable view of the anti-tax movement.

Forty-seven percent say they view the Tea Party in the same negative light as the Democratic and Republican parties, according to the CNN/Opinion Research survey. The Tea Party numbers are up 21 percentage points from January 2010.

The poll finds 32% of Americans have a favorable view of the Tea Party, down five points from December, shortly after movement supporters helped elect a GOP majority in the U.S. House

The CNN poll comes as the founder of Tea Party Nation ponders whether the movement is fading since its anti-tax rallies of two years ago grabbed headlines and drew millions of people into activism. Plus, the Tea Party Patriots are hosting a Washington rally tomorrow to call for less federal spending.

Judson Phillips of Tea Party Nation wrote the movement may be experiencing a lull now because the presidential race hasn't fully heated up and the economy -- though bad -- may not be so terrible that people will take to the streets "for much more forceful protests." A revival of the Tea Party movement is coming, he says.

We'll see if the Tea Party's long-held principles of lower taxes, reduced spending and minimal government intrusion will come into play tomorrow, when the Tea Party Patriots host a "Continuing Revolution Rally" in Washington.

The rally is timed to influence contentious budget negotiations between the House and Senate to avoid a government shutdown on April 8. It will feature such Tea Party favorites as GOP Reps. Michele Bachmann, Mike Pence and Jim Jordan.

It was originally scheduled for the steps outside the U.S. Capitol, but has been moved to the Robert A. Taft Memorial just north of the complex.

"Members of Congress have abandoned their service to the people by passing continuing resolutions instead of cutting the $100 billion they pledged," said Mark Meckler and Jenny Beth Martin, national coordinators of the Tea Party Patriots. "...A real budget will spark a national debate on the role of government, and that's what the American people want."
