Third rail redux…As the White House pushes for a renewed GOP advance on Dubya’s privatization scheme, the big Congressional names — Frist and DeLay — have started hedging their bets. Hmmm…if the Republican leaders are already acting this shaky, the ground troops must be contemplating a full-on rout.

Remember ’93? It’s payback time.
