Dafuq? Really? That is creeee-pay and weird.

I didn't see Potato Joe from the front but he looks stockier (flak vest?) and is way more animated than normal. The body doesn't look like him, too tall and stocky.

This would make a lot of sense. There is no way they can parade around the real Joe in public, let alone have him in meetings with foreign leaders, making military decisions, etc. So if Potato Joe isn't performing the duties of the presidency...than who is?
