Who is that Rockstar?

A crowd of 75000 people have gathered in Portland, Oregon.



The Washington Post describes the above scene as follows:

'The scene suggests this is not an exaggeration. The sea of heads stretches for half a mile along the grassy embankment, while others watch from kayaks and power boats bobbing on the Willamette River. More hug the rails of the steel bridge that stretches across the water and crowds are even watching from jetties on the opposite shore.'

Who could it possibly be? What could the occasion possibly be? So many people, so much anticipation - a concert perhaps?

Here's another pic:



Upon closer examination, the centre of attention appears to be one particular individual - on the stage at the front.

He is black, he is a politician and he is the front-runner for the Democrats' nomination for President of the United States. An unlikely scenario. Believe.
