Days before the 50th anniversary of Dr. Martin Luther King Jr.’s famed “I Have a Dream” speech, the last surviving speaker from that historic day said King wouldn’t think his hopes for racial equality have yet been realized.

“Fifty years later, if Dr. King could speak to us, he would say, ‘We’ve come a distance. We made a lot of progress. You’re in the process of laying down the burden of race. But we’re not there yet,’ ” Rep. John Lewis (D-Ga.) told CBS’s “Face the Nation” yesterday.

“He’d be grateful to see an African-American as president of the United States. ‘It’s almost unreal, unbelievable,’ Dr. King would have said, ‘that 150 years since the Emancipation Proclamation, 50 years since I made the speech on the steps of the Lincoln Memorial, and look what you have done.’ ”

Former Secretary of State Colin Powell told the show that Americans should be “proud” of the advancements in civil rights since King’s speech capped the 1963 march.

“My thought is that this country’s come so far,” Powell said. “I mean, It’s easy to say that, ‘well, we’ve still got a lot of problems.’ And we do. But we should not overlook how far we have come since 1963.”

Also yesterday, Newark Mayor and US Senate candidate Cory Booker told NBC’s “Meet the Press” that his mother was involved in planning the original March on Washington.

“We, as a people, can never allow our inability to do everything, solving poverty, to undermine our determinations to do something.

And so I’m a child of a generation that said, ‘I’m going to do something to make this world a better place,’ ” he said.
