About 20 years ago, there was a great episode of "Cheers," featuring a city councilman who goes to the bar to ask voters for support. "Kevin Fogarty, City Council. I hope I have your vote on election day," he says. Frasier Crane asks, "And why exactly should I vote for you, Mr. Fogarty?"

The councilman replies, "Well, because I'm a hard worker, and I take a stand." Crane adds, "On what, exactly?" "The issues of the day," Fogarty replies. "Which are?" Crane asks. "The things that concern you and your family -- the most," the councilman concludes.

The folks in the bar thought this was a great answer, failing to notice that the candidate clearly had nothing of substance to say, and was simply faking his way past the questions, hoping no one would notice.

The "Cheers" episode came to mind last night watching Sen. Jeanne Shaheen (D) debate former Sen. Scott Brown (R) in New Hampshire. At one point, for example. moderator Chuck Todd asked about climate change -- Brown believes some of the crisis is "natural" -- and pressed the candidates on how best to reduce carbon emissions.

"I'm not going to talk about whether we're going to do something in the future," Brown replied, apparently confused about the purpose of a political campaign.

Remember, border security is one of the issues Brown claims to care the most about.

All of which led the challenger to make a striking claim.

Scott Brown's strategy in his New Hampshire Senate campaign has focused on claims that securing the border would prevent Islamic State militants from crossing into the United States. But when asked on Tuesday for evidence, Brown denied he ever made such statements. "With respect, I did not say that -- what I have said is ISIS is real," Brown, a Republican, said during the first televised debate of the New Hampshire Senate race.... "Is there a possibility?" he added. "It's been raised that there are opportunities for people to come through that border. What are their intentions, I'm not sure, but they have made it very clear that they want to plant a flag in the White House."

He added, "I'm not fear mongering."

In reality, Brown's denials about his claims are plainly incorrect. It was literally just last week that the Massachusetts Republican told voters, "[W]e have a border that's so porous that anyone can walk across it. I think it's naive to think that people aren't going to be walking through here who have those types of diseases and/or other types of intent, criminal or terrorist. And yet we do nothing to secure our border."

His claims were wrong on the substance, and for him to deny making these comments only adds insult to injury.

Sabrina Siddiqui added, "Brown has suggested on multiple occasions that ISIS terrorists could cross the southern U.S. border. Just last month, Brown raised the theory during an interview with Fox News."

As for the "Cheers" episode, it's probably worth noting that Kevin Fogarty ended up losing his election.
