"Bernie looked like he crawled out of a garbage can last night," Huntsman said on Friday's episode of "The View."
Huntsman argued that the debate "didn't move the needle at all" for her, saying: "For me, it was like an 'SNL' skit. Everyone played their roles."
"Some of the plans he's putting forth -- to me, just seemed like someone who wants to become an MSNBC contributor or wants to run for something else," she said.
Co-host Joy Behar disagreed, defending O'Rourke's rhetoric on firearms. "Beto is a guy who just witnessed people dying in El Paso. That's why he is passionate," she said.
She was referring to the Aug. 3 mass shooting at a Walmart in O'Rourke's hometown. During Thursday's debate, O'Rourke said: "hell yes, we're going to take your AR-15, your AK-47."
"We're not going to allow it to be used against our fellow Americans anymore," he added.
During the debate, O'Rourke's campaign released a new slogan: "Beto has a ban for that," which plays off a popular refrain of Elizabeth Warren's supporters: "She has a plan for that."
