If the Democrats were to switch back to their former selves (think of presidents such as John Kennedy or Harry Truman), it would change things. However many of their positions are now considered politically incorrect. As long as the conservative Republicans are blocked by the populists, and the Democrats have apparently adopted positions of militant opposition to religion (in general), capitalism and free enterprise, white privilege (a thinly veiled framework for encouraging anti-Jewish violence), and the military (needed in particular to keep us safe, as America’s primary enemies make it clear that they especially don’t like us), there isn’t much choice but to support Trump in 2020.
Note to CTLawyer above: What “Muslim ban”? That was campaign rhetoric that was never acted on. Unlike professional politicians who think before they speak and plan their lies carefully, Trump lets his mouth run and doesn’t take his rhetoric seriously UNTIL he actually has to do something. Trump banned people (not just Muslims) from countries whose governments weren’t willing or able to cooperate with the US in checking with immigrants (or tourists for that matter) were hostile to the US. None of the countries with large Muslim populations (Egypt, Pakistan, India, Indonesia, not to mention Saudi Arabia) were included. The claim of a “Muslim Ban” is an example of a “Big lie” from the Democrats, and you fell for it.
