Mediaite’s Joe Coscarelli captures this rather lengthy moment at Barack Obama’s appearance for Martha Coakley today. The big news here isn’t so much that a heckler appeared at a Coakley rally — with passions this high, it would have been news if one hadn’t — but that a series of hecklers threw Obama so far off his stride. It didn’t matter to the people who attended this rally, of course, but it’s a bit strange to see an experienced politician allow a couple of loud voices to interrupt for as long as this goes … and then to ask “Where were we?”

How long before Democrats start painting this as “thug tactics?” Or have they already? At least no one tackled any reporters.

Update: Via Noel Sheppard at Newsbusters, MS-NBC shot video of the protesters themselves:
