On Local Issues: Build a new sports arena for the Milwaukee Bucks

These projects don't work and are in fact bad deals for taxpayers. There is no statistically positive correlation between sports facility construction and economic development. And there are hundreds of such deals across the country.

Merits aside, the Walker initiative presents a test for the right, especially the Tea Party. They've been somewhat consistent in opposing sports subsidies. But Gov. Walker has been perhaps the most outspoken Republican about the need for clear principled actions, on social policy and economic policy. When you hold yourself to a higher standard, small inconsistencies are magnified. If Gov. Walker is to be the candidate of the true believers, the free market, Ayn Rand, and austerity bugs, he's got some explaining to do.
