I decided to do some research on politics and the origin of the Republican and democratic parties the other day. I was looking at a site that basically compared he two parties and even showed the popularities of each party by race and gender. I had learned that the Republican Party was formed and they were the driving force that helped abolish slavery, alongside Abraham Lincoln. The site also said that 90+% of African Americans today are democratic (that party was pro slavery at the time for the most part I guess). So I guess my question is how did the parties get so re-arranged? Why is it such a vile thing to be considered a Republican, other than the president sitting in office currently? I’m genuinely interested in informative answers, wasn’t sure if I should post this here or somewhere else. Thanks!
