Well to me Reagan was just a mouth piece for the Neo-cons that basically took over this nation for 20 of 28 years. He wasnt an overtly bright man, but he protrayed this image of nostalgic America which may have never even existed, and made people feel great about themselves. I mean he started exhibiting the first signs of alzeihmers in his first term, and it was obvious by the time he left office. I read somewhere that when cabinet meetings and NSC meeting were going on Reagan would have a huge jar of jelly beans putting them in smaller jars according to color, while his Cabinet and Bush would discuss what they were going to do.
Wow! I'm not sure where you read that but he was giving speeches including at the 1992 convention well into the 90's. That's wishful liberal thinking that he was like that while in office.
Compare his speech at the 1992 convention to his speech at the 1981 convention. I'm sure you can see some difference in both the sharpness of his words, his delivery, even his reaction. Very halting delivery, slow paced, and kind of unaware of the audience's reacton.
He according to most accounts started having memory issues around the late 1980s, and he was unofficially diagnosed with it in 1992, underwent a battery of tests and was diagnosed officially in late 1993. I don't believe he came out with the fact that he had it until August 1994, but already he was pretty bad--For example only minutes before his speech at his birthday that February, he had forgotten completely where he was and why he was there and some of his friends were afraid his speech would be embarrassing for him.
