Progressives' Urgent Question: How to Win Over Voters of Colorhttps://www.yahoo.com/news/progressives-urgent-win-over-voters-154409501.html
There's a reason Trump received the highest black vote, 12% of any Republican presidential candidate going back to 1976 when Ford received 15%. With the exception of G.W. Bush in 2000 and 2004, G.W. spoke Spanish, Trump's 32% of the Hispanic vote was the most received of any Republican presidential candidate since Reagan in 1984 who received 37%.
Percentage of the vote broke down via race to see if we have a trend going.
Whites,2012 Romney 59%, 2016 Trump 57%, 2020 Trump 58%
Blacks 2012 Romney 6%, 2016 Trump 8%, 2020 Trump 12%
Hispanics 2012 Romney 27%, 2016 Trump 28%, 2020 Trump 32%
Asian 2012 Romney 26%, 2016 Trump 27%, 2020 Trump 34%
Perhaps, just relying on demographics isn't the guarantee that the democrats think it is. It may be, but I suppose time will tell. Yeah, interesting article for those who read it.
