The reich comes out politicizing everything they can and then assaults the left because they feel the left started it. Kinda like one of the old sayings about making a lie be true. Tell it big enough and often enough and soon it is truth.
Everyone (it is assumed) is watching. Democrats want to get their digs on Trump in for the biggest crowd possible. They don't care about the deceased. Honoring the deceased is alien to their way of thinking.
ALL they want is to get their narrative out there.
Remember that little Democrat toady Rahm Emanuel said "Never let a good crisis go to waste". To him, what better time is there to politicize but at a celebrity funeral.
