Number of politicians in the US Senate?

Some might deny being politicians, but there are really 101 of them: the President of the Senate, and all 100 Senators.

Speaking strictly about elected officials there are 2 People elected per US State or Commonwealth- 100 Senators. And the Sitting Vice President of the United States is the official President of the Senate but he is only present in the Senate in the event of a tied vote or to preside over and certify the official vote count of the U.S. Electoral College.

The President Pro Tempore is commonly referenced as the President, or acting President of the Senate and that position is held by the longest serving member in the Majority Party.

So, really 100 but technically 101 if you count the VP.
