You're jumping to conclusions.
You don't know why the Dems lost the election.
I've heard part of it is because of the suppression initiatives the Republicans put in place between this election and the last.
Such as? (btw, the GOP made gains in almost every demographic that are normally DNC strongholds)
I think many people didn't vote for Dems because they were upset that USA was funding Israel in its demolition of Gaza, never mind that Trump is even worse for the Palestinians. Also many progressives were upset that the Dems didn't do a primary and just appointed Kamala. (the right wing campaign complaining about this worked). Also many left wing folk were feeling despondent about inflation and crime, even though the Dems had got control of inflation better than most countries and even though crime has gone very low. These people again listened to the propaganda of the right wing and believed the nonsense that it was spouting. And so they didn't feel enthusiastic to go to the election booths.
It wasn't because the left was going too far. That's just right wing nonsense.
There's a simple math exercise we can do to shed some light on that hypothesis...
If you had to give a ballpark estimate, which group has more people, farther-left progressives? or centrists?
A pew research poll indicated that only 12% of US voters consider themselves to be "Progressive Left".
Meanwhile, there's 38% identify as centrist/moderate.
So, if you look at the social issues and foreign policy and economic initiatives that are popular with each respective group.
Does trying to appeal to that 12% make sense if it comes with the potential risk of alienating a big chunk of that 38%?
The Democratic party are having a very tough time trying to get their message across to the public because the right wing media and social media are full of nonsense propaganda, and Democrat voters are much more likely to listen to the right and try to compromise than what right wing voters are.
That sounds like denial and scapegoating.
"The right wing media is causing it". That's a stretch.
If we look at the top 8 news outlets in the US
CNN
Fox News
MSNBC
CBS
ABC
NBC
Washington Post
New York Times
....so your theory is that because right wing news has 1/8th of the market share in the world of major-market news media, that's what did it?
So Democrats have 80% of the news media, most of academia and entertainment, in 2021-2023 run-up to election season, every social media outlet except one, and had tech companies helping censor right-wing viewpoints on their behalf.
....but they just "couldn't get their message across".
Sounds like a "them problem"
Seems like they have tool in the toolkit for getting across their message just fine, and maybe...just maybe, people have heard their message loud and clear and just really didn't like certain parts of it.
Are you even willing to admit at all that there's a possibility that there are certain aspects/policies within "progressivism" that simply just aren't that popular among 2/3 of the country?
