Kanye West -- Over a Barrel on Presidential Domain Name

Kanye West may have just made a young man a fortune by announcing his possible run for President.

Tramall Ferguson registered "KanyeForPresident.com" back in April on a whim ... thinking maybe one day Yeezy would make it in the oval office.

The 24-year-old recent graduate said he registered a few other domains, including "PeterGriffinForPresident.com."

After Kanye's announcement at the MTV VMAs ... Tramal's phone is blowing up with huge offers to own the domain ... upwards of $80k.

Tramal says he's holding out ... waiting for Kanye to call. He wouldn't say how much he'd charge, but he was clear ... Kanye's not getting it for free.

It'll take a lot more than a pair of those Yeezys.
