This isn't a recent phenomena. Bernie's statement calls out the Democrats behavior over the last 30 years which puts you right in the middle of the first term of Clinton. However, Clinton was the first Democratic executive that had a chance to really enact a strategic change in the Democratic party that was first formulated after the chaos and losses of 1968.
Before 1968, the democrat party was tightly knit with union interest and the selection of a presidential candidate was done behind closed doors by party bosses. This is how it was done in 1968 resulting in Hubert Humphrey. Hubert Humphrey was an establishment candidate and VP to a very unpopular president who decided not to run for a second term. Robert Kennedy was very popular, but assisted before the convention. There were other candidates, but Hubert Humphrey enters the race after the 12 primaries had closed, but before the convention. There were a lot of reasons for chaos at the Democratic Convention in 1968, but this was one. Humphrey was chosen in an undemocratic fashion by party bosses despite lacking wide support by the base. I'm not saying history repeated itself, but it sure rhymes.
So Humphrey loses. The next four years results in reflection buly the party, an internal document called the McGovern-Frasier report is created, the selection process becomes more democratic causing candidates to make a wider tent for an intra-party coalition resulting in the nomination of McGovern eho whose major focus was to get the US out of Vietnam. Major unions decide not to back him and, well, he gets his ass kicked.
More reflection and the Trilateral Commission conclude that "excessive democracy" had resulted in the erosion of economic and political stability. So unions are still important in America at this point, but there's a growing shift from an industrial society to a professional services society starting to happen. The members of the Trilateral Commission see this and start to court this group. Meanwhile, colleges increase enrollment accepting non-traditional students to matriculate.
Jimmy Carter, a member of the Trilateral Commission, is elected and enacts several neo liberal policies such as deregulating the airlines and creating natural gas markets. He fails a bid for a second term, but the tenor of what is yet to come has been sounded. Atari-democrats, young ambitious tech savvy, step to the fore and represented by someone like Gary Hart. He fails to get the nomination mainly because he had an affair and Mondale gets the nod. Mondale was an old school dem who supported labor and Carter's VP. He loses worse than McGovern in 1972.
In 1988, Dukakis runs trying to bridge the old Dems and the new Dems. Like riding two horses, he fails. That's four out five election losses. 1992, a young whipper snapper from Arkansas steps to the plate and wins with an outstanding 43% of the popular vote. Wait! How could be, you ask? You see, Nader isn't the only spoiler candidate. One free wheeling Texas business man named Ross Perot got about 20% of the popular vote. I still remember is slide presentation on network television.
But I digress. This administration, knowing they just barely won, does what anyone who hasn't won in a whole and makes radical changes. Good bye old guard and welcome the new way of ruling. One notable survivor of the purge was Joe Biden. They deregulate more industries and open more trade with NAFTA, CAFTA, China and help rebuilding a newly democratized Russia. Not all of this happened in the first term, but these were all important events. W campaigned on an isolationist strategy in response to much of this. From 1993 to 2013, we lived in the Clinton era. Biden isn't really aligned with it deeply. He's been the middle ground man and probably is more closely aligned to Mondale or Dukakis.
The stock market takes off during the first tech boom, but the vast majority of the spoils go to the professional class and the rich. The working class is doing better because everyone is doing better, but not keeping up. Meanwhile factories are closing and we aren't investing in infrastrcuture. Also, if you want your kids to have a future, send them to college. Can't afford it? No worries, here are some loans. It's for your children. Good luck!
It's during this time that you see them not resisting neocon war mongering. War mongering guts the working class. You see Obama not helping out the working class after the 2008 financial crisis. But who cares? The stock market is soaring! What do mean you don't have any extra cash to invest. Good luck!
2016 had primaries, but everyone knew they'd regret it if they got in the way of Hillary. It was her turn and we deserved a woman president. Biden regrets sitting this out. I don't know if he would have had a chance, but being VP, it would have been a fight of two different visions. Throw in Bernie and there's a real decision to be made.
Well damn... This was far too long. Hopefully it was an interesting read. Yeah, there's five examples in here, but the damage is far more subtle over the course of several decades. The working class, when unionized, were powerful. And politics were fucked up. Then we gutted them and an industrial base and shit's fucked up in a new way. No easy answers. Just grinding.
After 2022, the majority of the funding comes from never Trumpers.
