Prior to 1820, how did eligible citizens cast their votes in elections?

I would say, showing up to the place holding the election and using a show of hands for yes and no.

Ithink its bill of rights

The president of the united states does not have the authority to “limit” the power of the judicial branch. however, the president can influence the political direction of decisions made by justices on the supreme court through the nomination process when a position becomes available.i would say the best answer is that he can at least interpret the laws
