The Democratic Party is made up of various groups that do not have much in common. Blacks are not hispanics, and vice versa. Private sector unions are not public sector unions. A lot of effort has gone into trying to convince suburban women that it's mean to vote Republican. Meanwhile, there is a set of elite power brokers pulling everyone's strings.
One problem with this is that the hypocrisy has gotten too blatant, opening the door to Bernie Sanders and AOC and the radical left of the Party. The other problem with this cozy arrangement is that the power brokers have essentially gone insane in their attempts to get rid of OrangeManBad. Now consider what actions the Elite has taken and what they have done to the members of their coalition:
- The Elite has stiffed Bernie (twice), alienating his supporters.
- The Elite has sent their (white) radical street muscle into Black neighborhoods, burning and looting black businesses.
- The Elite hasn't really done anything at all for the hispanic community. Their support for communists has hurt them in Florida where Donald Trump is outpolling Joe Biden among hispanics (!).
- The Elite has pushed outsourcing (most recently the Trans Pacific Partnership treaty which Trump killed). Private sector unions have noticed.
- The Elite has pushed the virus lockdown which has thrown millions of restaurant employees out of work. Many of these folks belong to SEIU. Now that emergency unemployment benefits have run out - and restaurants are going out of business because of the continuing lockdown - you have to wonder if these people will start to wonder why they support the Democrats.
- Public Sector employees have done well, but the areas that locked down hardest are the areas where the government budgets are most in trouble. New York City is going to lay off 40,000 employees. The Elite has hoped that Biden will win and bail out the states and cities. Good luck with that.
- Lastly, suburban women are hit with a Democratic Party double whammy: schools remain closed in many (especially Blue) areas. Women see their family lifestyles massively disrupted, and potentially are forced to consider giving up their own job to home school their kids. At the same time they see radical rioters entering suburban towns. Rioters are filmed telling people to get out of their homes which will be taken as "reparations".
