I am as liberal as they get, and even I get bombarded with right wing memes and news via various social media. But yeah, I don't think the block parties are happening because of Trump. That stuff is going to happen because young people are just being young. But I also don't think young people partying poses any real threat to the states ability to 'control'.
But the handful of sparsely attended, astro-turfed lockdown protests, which were spun in the news as a ground swell of anti-lockdown support, were absolutely influenced (if not actively coordinated) by the right wing media and Trump.
And for the record, your original claim was that states are loosing control, so that is forcing them to open back up. And my claim, was that that is incorrect, they are making a political calculation. The governors are getting squeezed from the right by Trump-ism, and they are getting squeezed from within by their rapidly expanding budget deficits. And at this point, a second wave is unavoidable due to the poor responses around the globe and within the US, so the benefits of successfully eliminating the virus in any particular state have been greatly diminished. But at any point, if a state deemed it necessary, they could marshal the resources to enforce stay-at-home orders. There is no populist uprising threatening their illusion of control, as you seem to believe.
