Jim Carrey, President?

In this thread, it was suggested that Canada has been annexed by the US and Jim Carrey is president. Someone argued that he couldn’t since he was Canadian. (But I think that was the OP’s point in making Canada a part of the US.)

The US Constitution says:

I had read that Alexander Hamilton couldn’t’ve become president, since he wasn’t born in the US. But wasn’t he a citizen of the US at the time of the Constitution’s adoption?

What if:[ul]
[li]I’d been born at the confluence of the Grand and Gunnison Rivers (which then became the Colorado River) in 1830, when that area was still considered Mexico[/li][li]At age 50, in 1880, I wanted to run for president[/li][/ul]
Since the site where I was born is “now” a part of an admitted state (Colorado, 1876), am I a natural born citizen?

Or as to the OP: if the Great White North is joined to the US, can the Canucks then run for president, or only those born after it’s assimilation?

The early Presidents were all born British subjects. The key point is that they were all natives of the land that became the United States. If Canada (or even just Carrey’s native Ontario) becomes part of the US, then the same precedent would apply, I would think.

Seems to me the answer to all of your questions is Yes.
