I remember some years ago a news piece from the USA on how students got involved in Federal politics.

They had all the time in the world for marches, making posters, etc., but when a local candidate who they supported lost, the reporter had a meeting in a coffee shop, and asked "who voted"?

The looks around the table, and the fumbling answers told the tale.

On to yesterday. There were hundreds of thousands of women, and men marching. The three key states that turned the election for Trump were collectively won with I believe 55,000 votes.

I don't think it is a stretch to say that you could easily have found 55,000 non-voters in those crowds, if the numbers are even broadly accurate, that would  have been fewer than 10% of the turnout.

A continuing lesson for all...
