I think there was, the GOPe hated Reagan. He had only 2 challengers in the 1984 primaries: Former Minnesota Governor Harold Stassen who got 12,749 votes (0.19%), and former Ambassador to Paraguay under Nixon Ben Fernandez who received 202 votes (0.00%). Note: He was the 1st Hispanic to run for President, from either party, in 1980, 1984, & 1992. He was
the son of illegal immigrants.
