Here we have the last Republican nominee sagavely attacking the current front runner. It suggests to me that Republican leaders are worried the general election may be a lost cause. Maybe it is time for a rational pro-growth, pro-business party to emerge and leave the intolerant fringe behind. A rational pro-growth, pro-business party could embrace policies like clean elections, a universal health care system that takes the burden off employers, investment in education rather than prisons, a rational guest worker program, and a revenue-neutral carbon tax.
