Encouraging people to vote is not considered election interference anywhere in Federal law. Bribing them to vote for specific candidate is. But not simply encouraging voting. However encouraging people to vote is, in fact, one of the 41 examples that Media Research Center identified as an demonstrating Google's so-called election interference.
If you think I'm wrong about that I'm sure you can find a citation somewhere in Federal or state law that says encouraging voting constitutes election interference. In fact, I doubt there are even any commonly accepted vernacular definitions of election interference that would include encouraging voting as a form of election interference.
The point that is lost in all of this back and forth is that when one actually takes a close look, one-by-one, at the so-called examples of election interference cited my Media Research Center, they all fall apart. Every single one.
