Corner case:

What if he is impeached multiple times during his term?

Is this market based on the first impeachment only? Or can multiple "year" markets resolve YES?

Or is this line of questioning invalid and I don't understand how the government works well enough?

@Quroe Multiple markets can resolve to YES

Corner case:

Can a President be impeached posthumously or after they leave office?

I've been trying to hammer out all of the corner cases in a market of my own. It seems like a simple boolean state of being in office versus not isn't as cut and dry as it seems at first glance.

Will Trump's 2nd Presidential term last exactly 42 months?3%‌

The corner case I present above implies that, in the event of the unthinkable, the market may not have enough information to resolve.

This adds an implication to your purple market for "before leaving office".

@Quroe with regard to the first question about a President being impeached after leaving office, I will not close or resolve the market just because the president has left office. If the House chooses to impeach a President who has left office that will count for the purposes of this market. On the other hand, strong constitutional principles council against impeaching a president who has died accordingly resolve this market in accordance with that presumption, unless there is talk within two weeks after the president's death of impeaching them despite them being dead.

@AaronSimansky This is ambiguous. Does it mean:
a) In 2029, prior to him leaving office
b) At anytime prior to when he leaves office (expected in 2029)

@DanielTilkin @traders I just renamed it to make it clearer

By what authority do we ask, "is Donald Trump POTUS?"

I can imagine a world where he tries to stay in office past his term limit, and you get two camps of people arguing over whether or not he is or isn't still in office.

@Quroe and @traders It will go by whatever office the House says the person holds in the resolution of impeachment.
