ON FRIDAY the Wall Street Journal provided a wonderful bit of irony: despite the howls of indignation from the Democrats over private campaign spending, it turns out that the biggest sugar daddy is the American Federation of State, County and Municipal Employees (AFSCME), a public-sector labour union that spends almost all of its cash for the Democrats. AFSCME accounts for roughly 30% of spending from pro-Democratic groups. A piece from US News and World Report points out that, in total, "Big Labour" is spending more private cash than the Chamber of Commerce and American Crossroads (Karl Rove's outfit) combined.
Since the WSJ article most of the commentary has involved arguments over possible Democratic hypocrisy (pro, con), but that debate misses the point. The Democrats are electorally beholden to union support, and this often leads to bad policy.
