From NBC/NJ's Adam Aigner-Treworgy
McCain just called on his supporters to be respectful at his town hall.
"We want to fight, and I want to fight, but we will be respectful," McCain said to boos at first. "I want everyone to be respectful," he then said and people began to clap.
In response to a later question he added, "You can be respectful and point out facts," as he called on his supporters to point out facts to their neighbors but be respectful.
*** UPDATE *** McCain just added, "He is a decent person and a person who you do not have to be scared as president of the United States."
After that, McCain said of himself that he just thinks he'd be a better President of the the United States." Some in the crowd booed his statement and shouted, "No!"
More to come.
