My first video from the convention shows Merrick Alpert withdrawing from the Senate race about halfway through the roll call and endorsing Richard Blumenthal. I only just turned on my camera well into Merrick's speech, so I apologize for not capturing the whole thing. I'm sure the entire video is available somewhere on the CT-N website.
At that point Alpert had only garnered about 5% of the vote, and it was obvious that he wouldn't get enough delegates to reach the 15% threshold to force a primary. So he did the right thing and withdrew, and then made the classy move of endorsing Dick after a somewhat contentious campaign leading up to the convention.
I applaud Merrick for showing good judgment and facing the political realities of the race.
