The same 'dude' who then nominated Rockefeller RINO Sen. Schweiker the very next year at the '76 convention as his running mate...you may remember Dick Schweiker, he was "in PA" too...
Everyone involved in that ‘76 campaign cite the move to make Schweiker the VP the reason they lost the floor fight. Why did Reagan do it? To appease moderates and RINO’s. It never works.
