I applaud the thousands of people, many of them poor, who traveled from around the country to protest in Jena, La., last week. But what I’d really like to see is a million angry protesters marching on the headquarters of the National Republican Party in Washington.

Enough is enough. Last week the Republicans showed once again just how anti-black their party really is.

The G.O.P. has spent the last 40 years insulting, disenfranchising and otherwise stomping on the interests of black Americans. Last week, the residents of Washington, D.C., with its majority black population, came remarkably close to realizing a goal they have sought for decades — a voting member of Congress to represent them.

A majority in Congress favored the move, and the House had already approved it. But the Republican minority in the Senate — with the enthusiastic support of President Bush — rose up on Tuesday and said: “No way, baby.”

At least 57 senators favored the bill, a solid majority. But the Republicans prevented a key motion on the measure from receiving the 60 votes necessary to move it forward in the Senate. The bill died.

At the same time that the Republicans were killing Congressional representation for D.C. residents, the major G.O.P. candidates for president were offering a collective slap in the face to black voters nationally by refusing to participate in a long-scheduled, nationally televised debate focusing on issues important to minorities.

The radio and television personality Tavis Smiley worked for a year to have a pair of these debates televised on PBS, one for the Democratic candidates and the other for the Republicans. The Democratic debate was held in June, and all the major candidates participated.

The Republican debate is scheduled for Thursday. But Rudy Giuliani, John McCain, Mitt Romney and Fred Thompson have all told Mr. Smiley: “No way, baby.”

They won’t be there. They can’t be bothered debating issues that might be of interest to black Americans. After all, they’re Republicans.

This is the party of the Southern strategy — the party that ran, like panting dogs, after the votes of segregationist whites who were repelled by the very idea of giving equal treatment to blacks. Ronald Reagan, George H.W. (Willie Horton) Bush, George W. (Compassionate Conservative) Bush — they all ran with that lousy pack.

Dr. Carolyn Goodman, a woman I was privileged to call a friend, died last month at the age of 91. She was the mother of Andrew Goodman, one of the three young civil rights activists shot to death by rabid racists near Philadelphia, Miss., in 1964.

Dr. Goodman, one of the most decent people I have ever known, carried the ache of that loss with her every day of her life.

In one of the vilest moves in modern presidential politics, Ronald Reagan, the ultimate hero of this latter-day Republican Party, went out of his way to kick off his general election campaign in 1980 in that very same Philadelphia, Miss. He was not there to send the message that he stood solidly for the values of Andrew Goodman. He was there to assure the bigots that he was with them.

“I believe in states’ rights,” said Mr. Reagan. The crowd roared.

In 1981, during the first year of Mr. Reagan’s presidency, the late Lee Atwater gave an interview to a political science professor at Case Western Reserve University, explaining the evolution of the Southern strategy:

“You start out in 1954 by saying, ‘Nigger, nigger, nigger,’ ” said Atwater. “By 1968, you can’t say ‘nigger’ — that hurts you. Backfires. So you say stuff like forced busing, states’ rights, and all that stuff. You’re getting so abstract now [that] you’re talking about cutting taxes, and all these things you’re talking about are totally economic things, and a byproduct of them is [that] blacks get hurt worse than whites.”

In 1991, the first President Bush poked a finger in the eye of black America by selecting the egregious Clarence Thomas for the seat on the Supreme Court that had been held by the revered Thurgood Marshall. The fact that there is a rigid quota on the court, permitting one black and one black only to serve at a time, is itself racist.

Mr. Bush seemed to be saying, “All right, you want your black on the court? Boy, have I got one for you.”

Republicans improperly threw black voters off the rolls in Florida in the contested presidential election of 2000, and sent Florida state troopers into the homes of black voters to intimidate them in 2004.

Blacks have been remarkably quiet about this sustained mistreatment by the Republican Party, which says a great deal about the quality of black leadership in the U.S. It’s time for that passive, masochistic posture to end.
