In 1992, former Pres. Reagan spoke at the Republican Convention in Houston. It turned out to be his last appearance at a political convention. A year later, he went into seclusion until his death in June '04.
In Houston, or his last public speech at the GOP convention, Pres. Reagan said this:
"I hope you will let me talk about a country that is forever young..." (Ronald Reagan: Forever young By Roger Simon)
In 2008 and later, we've had debates at the Reagan Library. All of the candidates want to be the next Reagan. Why? Because Reagan was an optimistic fellow.
