What I have come to understand from trump's presidency is that there really aren't very many policy debates amongst American voters. Not really.
Like I have asked republicans why they don't like Pelosi and they don't actually have a policy reason. She passed health care that millions of people use, she passed a Consumer protection Agency that's returned billions of dollars to Americans, she passed a banking regulation bill after banks destroyed the economy and a stimulus package to save the economy.
No one actually disagrees with those things. A minimum wage, worker's rights, social security, medicare, Medicaid, environmental protections, etc none of that stuff is actually in dispute amongst most voters.
The fight in American politics is a question of who gets to influence American government and who gets helped by the government.
Sadly, republicans really and truly believe that black Americans, Latino Americans and Muslim Americans are a threat to the nation, and they don't want the government to help those citizens. They believe that helping those citizens will be bad for the nation in various ways.
And really and truly that's what the divide in politics is about. republican voters perceive that the Democratic party is enabling these groups of Americans that they believe are bad for America and they don't want those Americans influencing the government to help them.
Now instead of having that discussion, we get a lot of phony stuff about de regulation or small government or tax cuts or abortion or etc, stuff that republican voters don't actually care about which makes it impossible to address the actual thing in dispute in American politics.
