You're idealizing Reagan beyond reality. He declared amnesty for illegals, and in a sweeping fashion. Bush doesn't want to do that. As Gov. of CA, Reagan signed the most permissive abortion laws of any state. Reagan appointed Sandra Day O'Connor to the Supreme Court. He also ignored the Islamic threats that showed up at Khobar Towers and Achille Lauro.
Reagan is one of my all-time favorite Presidents. But the major way he gained success was to limit what he tried to do to just a few priority issues. Bush is doing the same. If Communism hadn't fallen (after he left office), Reagan would have been remembered as ordinary. Bush is taking the same risk with Iraq and the middle-East. He may or may not be successful in the end, but he's following the pattern.
(And, oh, if he only could speak eloquently!)
Reagan actually had well thought-out opinions based on his own experience. He was our best president of the 20th century.
His amnesty was supposed to be backed with border enforcement. Both parties have been criminal in allowing the invasion to continue and grow.
