But the Newark mayor may have done himself serious damage before he gets the chance to act on his long-held ambitions, thanks to his pointed criticism of the Obama campaign’s assault on Mitt Romney’s private-equity tenure, which he equated with the GOP using the Rev. Jeremiah Wright against Obama. Booker’s words, combined with his painful, videotaped walk-back hours later, may have done the Democrat more harm than good. …

Some Democrats, and Republicans, believe that the telegenic, African-American mayor emerged from the week — in which he called the attacks on Romney’s record at Bain Capital “nauseating” on “Meet the Press” — as a pragmatist, one who could work with the Republicans in the Democratic-leaning Garden State.

But while the mayor’s “No Labels” centrist appeal may work with donors and center-right voters, it will do little for him in a Democratic primary against, say, Sen. Frank Lautenberg in 2014 — especially if Obama is reelected, and holding onto a grudge.
