Trying to pin Trump's rise solely on a certain group of Democrats is silly and ridiculous.I don't dispute Biden in the midwest at all. And let's be honest: The south is Trump's strongest region as well. He should be lambasted because this is a different time. Again, this is not about Bernie. This is about the fact we nominated someone that was a part of the group that made the decisions the lead up to trump in the first place. And now, if we don't make sure we're on his butt, it could lead to someone like Tom Cotton being president. And Tom Cotton could easily win Georgia, or NC, or FL. Just like Trump issue. The pattern is clear here. We need to prevent fires instead of constantly putting them out.
You can't "prevent" anything. Politics is fluid. Each party has their strengths in different areas. Trying to cover every single base it would require to "prevent" another Republican president is damn near impossible.
