Bloomberg’s money helped, obviously, but let’s not lose ourselves in the results. One: Illinois’s second is one of the most Democratic districts in the country, one of few where a pure anti-gun message can win. Two: Halvorson ran in the 2012 primary, too, trying to take out Rep. Jesse Jackson, who was already sagging under the weight of scandal. Halvorson got creamed, winning 24 percent of the vote — similar to what she got last night. Three: The worry among Democrats was never that Halvorson would take a majority in the primary. The worry was that black Democrats would crowd the primary and allow Halvorson to win with somewhere between 25-30 percent of the vote.
