I caught half of the Republican debate last night, and I thought Rick Perry, just back from the Texas wildfires, did enough to build on, though he didn’t dominate his rivals as recent polling might have suggested. Mitt Romney was effective, though his attack on Perry for his “Ponzi” comment was off base. Social Security is a Ponzi scheme, in that it depends on ever new contributions to keep going, and when those payroll taxes dry up, someone will be left holding the bag. That someone is us. I walked away encouraged by the strength of the field but wishing for a star, someone who can take on Barack Obama. We need substance and sizzle.
