Dems promise status quo. America as a whole does not want status quo. Cost of living keeps going up while technology rips apart society in ways we would have never predicted a decade ago.
As long as the only alternative to Trump is status quo, Trump will always win. The DNC’s only real concern is maintaining the current power structure. But it’s like Blockbuster ignoring the rise of Netflix. The winds have changed. The future is going to be radically different for better and definitely for worse.
While there’s some element of truth to what you’ve said- the DNC is using the “End of Democracy” meme as one of their primary themes in their campaign messaging- I don’t think that had anything to do with this shooting.
Statistically speaking the vast majority of domestic terrorism comes from far-right extremists. We don’t know the motivations behind the shooter at this point in time, but the consensus seems to be so far that he was conservative.
I think it’s much more likely he was radicalized online and either
a) wanted to kill Trump to further polarize the political tension in an accelerationist sense (sort of like how far-right organizations were shooting both protestors & police during Euromaidan. Just to increase the outrage, the violence, etc).
Basically an attempt to weaken the regime
Or
b) he became a white supremacist and those tend to hate Trump. Go on stormfront forums and see what they say about Trump. They think he’s a jewlover, fake messiah, etc. They hate Jews, Trump loves jews. Therefore, Trump is a potential target.
Or
c) was just nutty plain and simple. Ie killing Trump would unite him with some cartoon character from Nickelodean in the afterlife.
All of those are vastly more likely than someone being radicalized by DNC messaging, I believe.
