The Emancipation Proclamation freed slaves in unconquered parts of the Confederacy. parts of the South already in northern hands. the border states of the Union. all portions of the United States.

unconquered parts of the Confederacy.

Explanation:

Instead of genuine concern for equality and freedom, Emancipation Proclamation was more of a wartime measure to retain the Union. Lincoln implemented the Emancipation Proclamation only to the rebellious Southern states. The federal government had little authority or capacity to implement the laws since certain states had already seceded and the war was ongoing. Moreover, the proclamation did not extend to enslaved people, in the border states, which had not seceded but slavery was practiced there.

the correct answer is "ethnic heritage".

a person's ethnicity can influence a lot the way he/she votes.

in the united states, for example, black people tend to vote democratic. it happens because the society builds a strong division among people, and equals tend to mingle and support equals. black people's votes in a whole will most certaintly lean towards a candidate or a party which supports the fight against racism.
