Take on purple Bernie

This week news came out to Bernie Sanders had suffered a heart attack which prompted many comparisons to Hillary's pneumonia three years ago which helped sink her candidacy.
What is more disturbing to me is that the first video I've seen of Bernie post ticker stopping, is one where he looks like Grimace. There is this weird purple aura around him which somehow makes him look for psychotic than usual
If Bernie has any lobs for his country or desire to see Trump defeated he'd drop out today, throw his full support behind Warren and clear the deck quickly
