Sen. Bernie Sanders on Saturday brought his campaign for the Democratic Party presidential nomination to the Exeter Town Hall.

Giant arched windows of the classic old brick building were cracked opened to let fresh air into the packed meeting room.

It was the same public hall where Abraham Lincoln spoke out in 1860 against the expansion of slavery. The town itself was the Revolutionary War capital of New Hampshire.

Today, Sanders called for a new “political revolution” to take back American from the billionaire class and rebuild the collapsing middle class.

Just as slavery was great issue dividing America in Lincoln’s day, today the growing wealth and income inequality in America, – greater now than at any time since the Gilded Age — is the overriding moral, economic and political issue of our day.

Inside the hall, all of the seats were all taken. The balconies were filled with people fanning themselves with Bernie placards in the close August air. Outside, the speakers blared Sanders’ speech to spillover crowd on the steps in front of the 1855 building. One man held an American flag. A lone young man heled a Rand Paul sign.

After nearly an hour-long speech, the senator took questions from the audience. His son, Levi, who lives in Claremont, New Hampshire, handed the microphone to those with questions.

“We are going to ask corporate America and the wealthiest people in this country to start paying their fair share of taxes,” Sanders said. “We’re going to send a message that enough is enough.”
