As Tea Party politicians prepare to take their seats when the 112th Congress convenes this week, they are already taking issue with Republicans for failing to hold the line against the flurry of legislation enacted in the waning weeks of Democratic control of the House of Representatives and for not giving some candidates backed by Tea Party groups powerful leadership positions.

Just a month ago, Tea Party leaders were celebrating their movement’s victories in the midterm elections. But as Congress wrapped up an unusually productive lame-duck session last month, those same Tea Party leaders were lamenting that Washington behaved as if it barely noticed that American voters had repudiated the political establishment.

Ron Johnson accused Democratic incumbent Russell Feingold (D) of being "on the side of special interests and lobbyists." [...]

But after defeating Feingold, Johnson himself has turned to K Street for help - hiring homeland security lobbyist Donald H. Kent Jr. as his chief of staff.

Johnson is not alone: Many incoming GOP lawmakers have hired registered lobbyists as senior aides. Several of the candidates won with strong support from the anti-establishment tea party movement. [...]

Sen.-elect Mike Lee (Utah) has announced that energy lobbyist Spencer Stokes will be his chief of staff. Tea party favorite Rand Paul (Ky.) has hired anti-union lobbyist Douglas Stafford as his top senatorial aide.

In the House, Rep.-elect Charlie Bass (N.H.) has named food industry lobbyist John W. Billings as his chief of staff. Billings was a senior aide to Bass during an earlier stint on Capitol Hill.

Rep.-elect Chip Cravaack (Minn.) has hired former U.S. senator and former lobbyist Rod Grams as his interim chief of staff, though aides have said the posting is probably not permanent. Grams's lobbying clients from 2002 to 2006 included 3M, Norfolk Southern and the Financial Services Roundtable, records show.

Other incoming GOP lawmakers who have recruited staff from K Street include Robert Dold (Ill.), Steve Pearce (N.M.) and Jeff Denham (Calif.). John Goodwin of the National Rifle Association, one of Washington's most powerful lobbying groups, has signed on as chief of staff for Rep.-elect Raul Labrador (Idaho).

When Republicans take over the House next week, they will do something that apparently has never been done before in the chamber's 221-year history:

They will read the Constitution aloud.

And then they will require that every new bill contain a statement by the lawmaker who wrote it citing the constitutional authority to enact the proposed legislation.

"I think it's entirely cosmetic," said Kevin Gutzman, a history professor at Western Connecticut State University who said he is a conservative libertarian and sympathizes with the tea party.

"This is the way the establishment handles grass-roots movements," he added. "They humor people who are not expert or not fully cognizant. And then once they've humored them and those people go away, it's right back to business as usual. It looks like this will be business as usual - except for the half-hour or however long it takes to read the Constitution out loud."
