It's Hard Out Here For A Clinton

AP’s David Espo reports:

WASHINGTON – Sen. Barack Obama won caucuses in Nebraska and Washington state and moved ahead in the Louisiana primary Saturday night, slicing into Sen. Hillary Rodham Clinton’s slender delegate lead in their historic race for the Democratic presidential nomination.

The Illinois senator was winning two-thirds support in both caucus states.

Returns from the first handful of Louisiana precincts showed him leading, a black man hoping to extend a string of Southern primary triumphs that already included South Carolina, Alabama and Georgia.

Other than the usual leftwing obsession with identity politics, why the curious gratuitous reference to Obama’s race in that last paragraph?

Update: On Bloggingheads.TV, Mickey Kaus ponders if Obama is too far to the left to win in the general election.
