This is where we are in American politics. Donald Trump, Jr. is sent out to warm up the crowd last night in Orlando for his father, and in the course of his remarks, he takes a shot at Joe Biden’s quest for a cancer cure. You may recall Biden’s son died from brain cancer. But Trump, Jr. went there.

Adding irony to Trump Jr.’s remark is the fact that his dad promised to cure cancer just three hours after Jr. made fun of Biden for the same thing.

Donald Trump also promised to eradicate AIDS and put an astronaut on Mars.
