People tend to forget about Reagan until the 1980's for some reason, but he was also a beneficiary of Buckley's purge and more acceptable than Goldwater outside the Party loyalists.
They also forget that while Governor he had a reputation for compromise, and even doing things that he was against, because "the will of the people" spoke.
He signed into law sweeping abortion bills and others, saying as he did so he was against it but he was not going to go against the wishes of the people of the state. And he even had a good relationship with the Democrats in the state, a far cry from the adversarial positions both parties take today.
Hell, he even appointed Democrats into key parts of his administration, including the Secretary of the Navy.
