There's this famous out-of-context Churchill quote of "Never let a good crisis go to waste."
Well, the Dems, former masters of tragedy exploitation, managed to fuck up their response to both Uvalde and the Buffalo shooting because they're apparently unable to keep their unhinged hatred towards le evil white republicans in check, which instantly alienates the moderates who would usually be susceptible to this type of messaging.
Buffalo fell out of the news cycle in two days despite the fact that it had everything they needed to push for gun control and domestic terrorism regulation. The same will probably happen to Uvalde.
The Hillary-era Democratic Party would have milked these tragedies for months.
