I do not know of a single person who says they consider Reagan a RINO. Can you name people who do?
Reagan was pro-life and appointed pro-life judges.
Reagan attempted to control Federal spending but was fought at every step. He instituted the Grace Commission which identified substantial savings. He also needed to rebuild the military which was underfunded by Carter and the Democrats. Had Reagan not been president spending would have increased more.
He agreed to the Simpson-Mazolli Act which was a mistake. He enforced border security far more than any president since.
Reagan aggressively fought abortion and even wrote a book on abortion as the sitting president.
entropy12 is confusing him with Mitt Romney.
