That was an interesting exchange and eemonstrated the difference in the thinking of a Liberal vs a Conservative. Rush's response was not really included except in the few words between the statements of the caller.
When Reagan came to office, the country was a mess. When he was re-elected, he came within .18% of the votes in Minnesota of carrying every state in the union. There has never been a more decisive victory in history. The caller may or may not have known this, but it strikes any challenge to the impact Reagan had on the country moot.
Reagan changed the way that Americans thought about themselves and about the country. This conversion of attitude crossed party lines, economic stratas, race, religion and gender. He ushered in the period of the "Peace Dividend" that cut back military spending and helped to lead to the boom times of the 90's.
The caller called out various details that the Right likes to use as litmus tests. He set up the false gambit that if this is true than that is true. If these are the tennets of the Right then Reagan cannot be a hero of the Right because he did not champion these petty issues.
In truth, Reagan was a hero to the country and the country knew it. .18% of the vote in Minnesota is all that kept Reagan from carrying every state in the union. His opponent was from Minnesota and he almost did not carry his own state.
What might we gleen from this?
