Impeached? I don't think that can happen in this country. Instead I think over 50 million Americans are going to vote for him to remain President for another 4 years.
The chance to impeach a sitting President was greatly diminished in 1913 when the Constitution was changed to allow the popular vote for Senators. It takes 67 votes in the Senate to actually convict and remove.
The original language:
Article I, section 3, “The Senate of the United States shall be composed of two Senators from each state, chosen by the legislature thereof for six Years; and each Senator shall have one Vote.” The election of delegates to the Constitutional Convention established the precedent for state selection. The framers believed that in electing senators, state legislatures would cement their tie with the national government, which would increase the chances for ratifying the Constitution. They also expected that senators elected by state legislatures would be able to concentrate on the business at hand without pressure from the populace.
