A REPORT FROM THE SCOTT BROWN RALLY AT WORCESTER: “It’s an absolute mob scene. The police have closed off the streets. It’s mind blowing. The hall is already full, and it holds 3,000 people. There may be another 1,000 people outside.”

Meanwhile, reader Sean Fitzpatrick writes: “Pictures don’t do justice. Nothing like this in Mass since JFK. Worcester rally starts in thirty minutes and the streets are already packed.” Here’s a pic.

UPDATE: Fitzpatrick sends another picture from inside the hall, and comments: “If the Brown campaign were worried that they wouldn’t fill the hall then they needn’t have. It is standing room only and the hall management is concerned about OVERcrowding.”

I like the “Whole World Is Watching” sign at the lower left. Yep. And sometimes via cellphone pics.

ANOTHER UPDATE: Meanwhile, reportedly, Coakley can’t fill a hall. “Martha Coakley and Barack Obama held a rally today in Boston. They couldn’t fill the hall. . . . It holds 3,000 and frankly only 2,000 to 2,500 showed up.”

UPDATE: DaTechGuy says that Cameron is wrong and there were plenty of people to fill the hall. “Cameron was inside and I wasn’t so I don’t doubt that he saw a hall that was not filled, but it wasn’t for lack of supporters as at least 500 people that I presume were Coakley supporters were not let in. I know since I was in the middle of them. In fact I personally spoke to a woman with a cane and a pronounced limp who had been passed through but was sent back due to fire limitations. (more on her later tonight). Perhaps it was a question of security. There were easily more Brown people outside protesting than Coakley people waiting to come in (more on that later) so maybe they were worried about screening out people who opposed the president and the candidate getting in so the campaign had to keep a tight leash to avoid mass heckling.”

More from the Northeastern event here, including an interview with Reason’s Michael Moynihan.

And I guess they were right to worry about hecklers. “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?'”
