They have bad production people setting up the stage.
I hear shitty sound, poor microphones, shitty lighting. It's like the lighting is burning their eyes on stage. I've been on camera several times with a TV production crew. Don Jr looked like he was blinded by the lights, if your eyes haven't adjusted to a bright light you might tear up or look squinty.
This looks like high school production value.
For instance, look into the speakers eyes. You'll see a reflection of light. No soft boxes, not even several lights. It's one bright spotlight from near the camera. This will also make you look a lot older. The difference is take a picture of your wife on a full sunny day, or on a partial cloudy day. The softer light will make her look young. This looks like they were sabotaged.
If you want someone to look like they're having a bad hair day, give them a strong back-light to make the frizzy hair pop.
Remember how they shined a red light over Trump to make him look more orange?
By contrast Pence did had a video prerecorded. That video was well done, and quite the contrast from the rest.
