President Obama and Meek Mill now have something in common -- they've both dissed Drake.
The prez sat down with YouTube star Adande Thorne ... who asked, "If Drake and Kendrick Lamar got in a rap battle, who do you think would win?"
Most hip-hop fans might pause, but BO quickly said Kendrick's his man. Okay, you might think he's gotta go with the American guy who happened to visit the White House recently, right?
Or should he have gone with the MC who has way more hits?
