Reagan’s fault in 1986 was his belief that the Congress sincerely intended to secure the border. History has proven that his trust was misplaced. You can be sure that if Reagan had a do over, that he wouldn’t be fooled the second time.
He still signed amnesty and was a conservative and probably one of the 20th century greatest presidents
Also Rand’s plan for what its worth is to secure the border and have progress voted on by Congress.
So he’s trying to learn from that misplaced trust.
