Twitchy has a comparison of the front pages of the New York Times and New York Post, both of which deal with the assassination attempt. NYT uses the same photo as NYP but crops it to remove the US flag flying behind Trump.
The Times certainly won't associate Trump with the United States in any way; the Post is proud to do so. The Times is pretentious trash and acts like a wholly owned subsidiary of the DNC, the Post is flashy but basically sound.
That photo, most certainly including the flag, will be famous and likely featured in Trump's campaign ads. I will risk a prediction, yesterday's would-be assassin has just about guaranteed Trump's election to a second term. If Trump has coattails, maybe a clean sweep too?
