I'm not White or tanned enough to be a Republican!

The Republicans haven’t had a single African-American in the Senate or House since 2003 and have had only three in total since 1935. Their anxieties about a rapidly changing America are well-grounded.

If Congressional Republicans want to maintain a politburo-like homogeneity in opposition to the Democrats, that’s their right. If they want to replay the petulant Gingrich government shutdown of 1995 by boycotting hearings and, as John McCain has vowed, refusing to cooperate on any legislation, that’s their right too (and a political gift to the Democrats).But they can’t emulate the 1995 G.O.P. by remaining silent as mass hysteria, some of it encompassing armed militias, runs amok in their own precincts. We know the end of that story. And they can’t pretend that we’re talking about “isolated incidents” or a “fringe” utterly divorced from the G.O.P  74 percent of Tea Party members identify themselves as Republicans or Republican-leaning independents, while only 16 percent are aligned with Democrats.

Are these politicians so frightened of offending anyone in the Tea Party-Glenn Beck base that they would rather fall silent than call out its extremist elements and their enablers? Seemingly so, and if G.O.P. leaders of all stripes, from Romney to Mitch McConnell to Olympia Snowe to Lindsey Graham, are afraid of these forces, that’s the strongest possible indicator that the rest of us have reason to fear them too!
