The problem with all of it? It’s rare that a president moves public opinion on an issue, especially when that president is not very popular. (For more on that, see Ezra Klein’s great piece in the New Yorker.) And Obama, at last check, is not terribly popular.
There is, however, one group with which the president is extremely popular.
In the Post-ABC poll, 65 percent of black voters strong approve of the president’s performance. (By contrast, 38 percent strongly approved of the so-called “first black president,” Bill Clinton, in the Spring of 1996.)
Since Obama came out in support of gay marriage, everyone and their mother has mused aloud about whether it might jeopardize turnout in the black community, which has historically been strongly opposed to gay marriage.
