It's always fascinating that more people don't understand the racism implicit in comments like this. It's almost as if a black vote should only count for half!

President Barack Obama was not amused by Mitt Romney’s 2012 presidential election concession call, according to a new memoir.

In “Believer: My 40 Years in Politics,” former senior Obama adviser David Axelrod writes that the GOP candidate implied on the call that Obama had won because of his popularity in black communities, according to the New York Daily News, which acquired an advance copy of the book.

Obama was “unsmiling during the call, and slightly irritated when it was over,” according to Axelrod.

“‘You really did a great job of getting out the vote in places like Cleveland and Milwaukee,’ in other words, black people. That’s what he thinks this was all about,” Obama said after he hung up with Romney.

The memoir, set to come out on Feb. 10, goes behind the scenes of other high-profile political relationships.

One part of the book describes the awkward relationship between former White House chief of staff Rahm Emanuel and Obama adviser Valerie Jarrett — a longtime friend of the Obama family — as Emanuel felt as thought he had to “manage the president’s best friend.” Emanuel helped campaign for Jarrett to inherit Obama’s vacant Senate seat to avoid the discomfort, but Obama kept Jarrett in the White House.
