Who in the roman republic had the right to vote and become a consul?

The patricians had the right to vote, as did the plebeians and equites and all the Roman citizens of the first class. Rome was a republic and all citizens could vote, depending on their class of citizenship. As far as becoming consul, anyone could run for the office providing he had completed the other offices leading up to consulship. In the later republic there was a law that one consul had to be a plebeian.
