Lloyd Erbaugh had barely gotten rolling before the chair intervened.
"OK, OK, you're done!" said Scott County commissioner Tom Wolf, banging his gavel. "This isn't going to be the forum for endorsing people or denouncing people."
The three men whom Erbaugh was about to tear into voted to deny him the chance. And the moment will echo for months, because all three face opponents this fall.
"You're changing 'open forum' into something else, just like that?" asks Brent Lawrence, Wolf's opponent in the November election. "That is monumental."
But he concedes that no one is dying to see a parade of speakers lining up - at a meeting that is supposed to be devoted to the public's business - to sound off on their own political opinions.
Indeed a range of civic leaders across the south metro agree that it is a delicate task to preserve freedom of speech without letting public events and public spaces turn into a mess.
That includes political signs scarring public rights of way. It includes allowing the Fourth of July parade to turn into a nonstop political advertisement. It includes a new breed of social media that can curdle into snide potshots.
All of it heats up in campaign season, many agree.
