It'll be hard, they're both pretty close. Both neoconservatives since 1991, Bush doctrine, PATRIOT Act, economically on the right (to different degrees, though) The only differences I can tell are that:
1. My mother is more socially liberal than my father, she is pro-LGBT and pro-choice, as well as pro-amnesty, while my father is none of those.
(My mother is more socially liberal)
2. My father hates any type of government spending except military and police. My mother believes in a reasonable amount of safety-net or welfare, while my father wants all social programs cancelled, essentially.
(My father is more economically hard-right)
3. My father is more hawkish than my mother. Wants to liberate Iran, Syria, North Korea, Zimbabwe, Cuba, Venezuela, etc. My mother is still supportive of the wars in Iraq or Afghanistan, but isn't too pro-invading everything.
(My father is more hawkish than my mother)
4. My mother is strongly Catholic, while my father hates religion and is a deist.
(My mother is more religious)
5. My mother is a permanent Never Trump-er, while my father started out as a Never Trump-er and switched to supporting Trump after the Republican National Convention in 2016. Mother voted for McMullin, father voted for Trump.
(My mother is Never Trump, my father is supportive of Trump)
