Scott Arnold, the Iowa gay voter who Newt Gingrich told to support President Obama, has said Gingrich made him feel like a “second-class citizen.”

Gingrich made the comment during an event Tuesday at Smokey Row coffee house in Oskaloosa.

Arnold, a Democrat and an associate professor at William Penn University, told the Des Moines Register that when he approached Gingrich on the topic of gay rights, the former House speaker told him to vote for Obama.

“When you ask somebody a question and you expect them to support all Americans and have everyone's general interest. It's a little bit frustrating and disheartening when you're told to support the other side. That he doesn't need your support,” Arnold said.

The Gingrich campaign has denied reports that he said gay voters should support Obama's re-election campaign, insisting that he was only referring to voters who view gay marriage as a central issue.

During an appearance on MSNBC's The Ed Show, Arnold said he was very surprised by Gingrich's response.

“It was almost as if he drew a line in the sand saying, you know, I don't want your support,” Arnold said. “Go vote for this other guy because there's no place for you in my, you know, my presidency. There's no place for you almost in a sense, you know, as an American.”

“If he wants to be president, he should be president of all Americans. And yeah, that did make me feel like a second-class citizen. Absolutely.” (Watch the exchange at MSNBC.)
