While it barely scratches the surface of Congressional noodling, it does give one pause.  What a rat’s breakfast this is.  When you hear “Progressives” and “Liberals” and Democrats whine and wail about the Koch Brothers and Crossroads and Karl Rove, keep in mind that Democrats wrote these laws principally to aide their Union thug friends and other like-minded true believers.

Perhaps the best punishment of the I.R.S. and Obama Administration miscreants would be to eliminate all but 501(c)(3) status and assure that it is enforced one hundred percent, in full, all of the time for education institutions, charities, including the arts, and most important, churches.
