In all things from taxes to government growth the Republican party has been infiltrated by "former" democrats that look to the giant breast from DC to feed all the nipple people. The best tag line I've seen describes the current candidates... "The 'p' in Democrat stands for patriotism." 'nuff said.
Well Trent Lott used to be a Democrat. A lot of these former Democrats are still Democrats on spending. Yes, they are all socially conservative Southerners, but still Southern New Dealers.
