Why did the issue of voting lead to another constitutional amendment in the late 1800s?
congress decided to extend voting rights to white women.
african americans had achieved equality in most other areas.
poor white southerners were blocked from voting by poll taxes.
congress was worried that white southerners would stop african americans from voting.

The correct answer is the last one: Congress was worried that the white Southerners would stop African American from voting.

The 14th amendment (1868) granted former slaves US citizenship. It also stated that they wouldn't deprive any person from freedom, life or property without the due process of law, they wouldn't violate any citizen's privilege or inmunity and should guarantee to every citizen equal protection of the laws. The 15th amendment (1870) granted African American the right to vote, prohibiting the use of race or color as a reason to deny someone their legal right to vote.
