Sadly, many in the GOP seem to have returned to their old ways...
Reagan's style of leadership was a throwback to a populist style that might have seemed anachronistic when compared with modern politics, but it crossed party lines. His message really was about style over substance and ideas rather than agendas.
That may have been more the case in Reagan's second term, then his first term, but I don't really agree with your assessment.
Reagan came into office with a focused agenda that was packed with substance. The Reagan plan was to restore a failing economy, advance tax reform and limited govt, rebuild the military, end the Cold War and revive the American spirit.
When Reagan left office, the economy was soaring, inflation, interest rates and unemployment came tumbling down, income taxes were way down, social welfare and entitlement spending was reduced, the military was ready for bear and the American spirit was alive and well. And most importantly, Reagan won the Cold War, dismantling the Soviet Union and Euro-communism.
