3. though the 15th amendment extended the right to vote to other citizens of the united states, what methods did some states use to restrict voting rights?

When poll taxes, literacy tests, "grandfather clauses," and "white primaries" did not stop blacks from registering and voting, intimidation often did the job. An African-American citizen attempting to exercise his right to vote would often be threatened with losing his job. So the poll tax, literary test, grandfather clause, the white primary, and intimidation/threats.

Hope this helps!

depending on what kind of map for example a pltical maps works in many ways this iss how it works it shows the areas and places the democratics and the repbulcicans reside for example if   texas chooses trump for president there a republican state and if   califronia chooses hillary there a democratic state.

this is true many people think today that blacks should be slaves also known as rasisim calling them many insults from slavery the idealogy of the south still exsist in some parts but not all
