People - and the media - do this all the time. There are videos out there that quote Trump's policies, and tell people that they are Obama's. Then ask if they agree with it. They said, "Of course!"
They do it the other way around as well.
I find it is a lesson to everyone. People need to stop being so robotic about how anything on MY side is good, or THEIR side is bad. Also, if people slowed down long enough and stop automatically taking sides? They might find there are issues and statements that the 'evil' side has that you might actually agree with.
It does show the highly partisan divide within the country that seems to be encouraged, and dumb blindness that goes along with that. lol although since we are so blind to this? People would start bickering about who is more blind - our side or their side - instead of owning the obvious.
