The threat of sharia, or Islamic law, to America's cities, towns, and way of life in general is going to be a major debate topic among Republican presidential candidates this cycle. More than a dozen states have been working to pass anti-Sharia laws, and we should expect to see more state ballot measures in 2012. It's a big thing in Republican politics these days. So wait until GOP primary voters hear about Tim Pawlenty's old plan to boost sharia-compliant mortgages, so Muslims could own houses! Oh, yikes.
