Democratic Wave in Congress Further Erodes Moderation in GOP By Zachary A. Goldfarb, Special to The Washington Post

[T]he Democrats’ victory in the midterm election accelerates a three-decade-old pattern of declining moderate influence and rising conservative dominance in the Republican Party. By one measure, the GOP is more ideologically homogenous now than it has been in modern history. The waning moderate wing must find its place when the Democratic majority takes over in January.

“The irony of this election is that the public, in seeking change, has . . . weakened the center,” Leach said recently. “In a sense, what has occurred is the strengthening of the edges of the parties.”

Eight of the House’s 20 most moderate Republicans lost their seats: Rob Simmons and Nancy L. Johnson (Conn.); Jeb Bradley and Charles Bass (N.H.); Michael G. Fitzpatrick and Curt Weldon (Pa.); Sue W. Kelly (N.Y.); and Leach. Also, moderate GOP Rep. Sherwood L. Boehlert (N.Y.), is retiring, and he will be replaced by Democrat Michael A. Arcuri, the Oneida County district attorney.

On the Senate side, the defeat of Lincoln D. Chafee (R-R.I.), a critic of the war who declined to vote for Bush’s reelection in 2004, underscored the same trend.

By one measure, the 110th Congress will have the fewest moderates since the 19th century. …

An important factor in the Democrats’ victory in the midterm election was that independent and moderate voters abandoned the GOP in droves. Since the 2002 midterms, support for the Republican Party has declined seven percentage points among moderates and nine percentage points among independents, according to exit polls.
