Shortly before Rep. West went off the rails with his accusations of communism in the Democratic Party, political scientists Keith Poole and Howard Rosenthal, who have long tracked historical trends in political polarization, said their studies of congressional votes found that Republicans are now more conservative than they have been in more than a century. Their data show a dramatic uptick in polarization, mostly caused by the sharp rightward move of the GOP.
If our democracy is to regain its health and vitality, the culture and ideological center of the Republican Party must change. In the short run, without a massive (and unlikely) across-the-board rejection of the GOP at the polls, that will not happen. If anything, Washington’s ideological divide will probably grow after the 2012 elections.
In the House, some of the remaining centrist and conservative “Blue Dog” Democrats have been targeted for extinction by redistricting, while even ardent tea party Republicans, such as freshman Rep. Alan Nunnelee (Miss.), have faced primary challenges from the right for being too accommodationist. And Mitt Romney’s rhetoric and positions offer no indication that he would govern differently if his party captures the White House and both chambers of Congress.
