The ones in the video linked to The Hill article are a MIG-21 at the start and F/A-18's later. I guess they just were looking to put some kind of fighters in their article.
Whoever put the MIG in the Trump campaign ad is an idiot. You'd think someone would scrub these things before they just started pulling random pictures of jets off the internet.
Maybe. But I see four hardpoints on each wing of your Mig-35 but only three on what folks are calling the Mig-29 in the ad.
