Besides the president, who is the only nationally elected leader in the united states?

The correct answer to this open question is the following.

Besides the president, the only nationally elected leader in the United States is the vice president.

Every four years, US citizens have presidential elections to vote for President and Vice president. The political parties organize a Convention where the delegates decided the formula for President and vice president. In the bipartisan political system of the United States, the two dominant parties have been the Democratic Party and the Republican Party.

regarding the law, the 15th amendment was specifically designed thinking in the rights of black free men.

even though ratified on february 3, 1870, the promise of the 15th amendment would not be fully applied for a long time.poll taxes and literacy tests would allow southern states disenfranchise african americans. only in 1965 the voting rights for african americans would be actually able to vote in the south.

in 1965, president johnson signed the voting rights act, which aimed to overcome legal barriers that prevented african americans from voting as it was guaranteed by the 15th amendment to the u.s. constitution.

these acts divided the south into five military districts.
