a few things make Bush scarier - by far - one - he is still President - we survived Reagan and his handlers, though the legacy still does harm

two - Reagan was/is a bad actor, reading what was put in front of him convinced some people that there was more there than there was - there is an interesting side note to this in one of Oliver Sacks' studies, a group of brain injured patients who develop an ability to detect insincerity, AKA 'lying', in the facial expressions of people used to laugh hysterically whenever Reagan came on the tube because they could see he was lying, and what he was saying was so completely incongruous with what he believed. BUSH, on the other hand, has beliefs and is willing to act on them.

three - Bush's beliefs - anyone who actually professes to believe in Armageddon and the Second Coming has no business directing this country and the world toward it.
