Social conservcatives diss the Trumpster because he ahs flip-flopped on abortion, now being pro-life. I belive Reagan also was at one time pro-choice.
Not necessarily pro choice, but he was not ardently pro life either during his early days as governor since he did sign the bill that legalized abortion in Califiornia in 1967. He later regretted signing the bill into law and cited his inexperience as governor for signing the bill into law.

Trump flipped on too many issues, kinda like Romney.
As for Reagan’s position on life, here’s an excerpt from Mark Levin:
“Others have suggested that Reagan flip-flopped on abortion; this is also false. He advocated a health exception (for the life of the mother) which, as he explained later, was exploited to include virtually anything. But he wasn’t pro-abortion. Giuliani and Romney were. And they are struggling with it today. Reagan learned that the exception became the rule, and he would oppose abortion of any kind from then on. To compare this with those who emphatically defended abortion on demand (and federal funding no less, in Giuliani’s case) is nonsense. ..”
