Also on Friday a busload of freshmen Democrats went to the White House to plead their case against sharp tax increases with the president and his chief of staff, Rahm Emanuel. The organizer was Rep. Gerald Connolly, the president of the freshman class whose Northern Virginia district is the richest in the U.S. as measured by median household income.

“There could come a time,” said Rep. Michael McMahon, a freshman Democrat from New York City’s borough of Staten Island, when Democrats are in open rebellion. “We will certainly see in the next few weeks where we are going.”…

“They’re just hanging themselves,” says Republican Rep. Sam Graves, who last year beat back a spirited challenge in his northwestern Missouri district, which includes suburban Kansas City, and said he is looking forward to a race on taxes in 2010.

The tax issue is presenting many new Democrats with a quandary as they struggle to get their political footing. “These members are going to have to make their own determinations on how to balance these interests,” said Maryland Rep. Chris Van Hollen, chairman of the Democratic Congressional Campaign Committee and himself a representative of the affluent suburbs of Washington.
