More are willing to admit they support the Tea Party

Sources said there is growing concern among Republicans that supporting any tax increase might provoke opposition from the Tea Party and hurt their reelection bids.   

The Tea Party has supported upstarts that have already unseated Sens.

And some Republican senators that aren't even up for reelection this year are tacking further to the right in their positions to keep the Tea Party from supporting a candidate in their home state.

"We are staring to see an interesting trend emerging from the [poll]," said Vik Rubenfeld, who oversaw the survey. "The number of Tea Party supporters who are willing to endorse the movement publicly has jumped seven points in one month, steadily rising from 34 to 41 percent. Meanwhile, overall support for the Tea Party remains stable among likely voters." 

The poll was conducted by PJTV, a division of Pajamas Media, on Sept. 5. Poll results can be found at
