Perhaps you mean 'vote reactionary', as the religious tend to do? Voting conservative means the Democratic party these days - general support of institutions, the United States's standing in the world, law and order, individual freedoms, fiscal responsibility. The contemporary Republican party has rejected these things, instead focusing on some imagined idyllic past and pushing for radical change towards it. The Democratic party certainly has its things it wants to change, but they're much more incremental and not the sweeping sea change of the current Republican agenda.
