I know it is a long shot but it is possible that in just two years the USA will have a democratic president. It would require that the Democrats win the majority of the House of Representatives. Then they could start an Impeachment of both Trump and Pence. I would think by that time, it would be easy to come up with many reasons to impeach Trump. It might be a bit harder with Pence but possible. Then the Democrats will have to win 60 seats in the Senate which is possible. If both Trump and Pence are impeached, the speaker of the House who would be a Democrat will become president.
I know this is very hard to imagine but is it harder than imagining that Donald Trump would become president of the USA and the most powerful man in the world?
