"I unfortunately cannot support either major-party candidate, and I'm taking a look at the Libertarian ticket because it's headed by two former Republican governors," Collins said on CBS's "Face the Nation." 

"I may end up writing in the name of the person I think is best qualified to be our next president," she said. 

Last week, Collins said she would consider the Libertarian Party, but only if it were flipped with vice presidential nominee and former Massachusetts Gov. Bill Weld leading the ticket.

"I know Bill Weld well, and I respect him a great deal," Collins said last Tuesday on CNN. 

Collins last Monday penned a Washington Post op-ed explaining why she wouldn't back her party's nominee for president, saying it wasn't a decision she made lightly. 

She wrote that Trump hasn't changed or evolved as a candidate and continues to dismay her with his "constant stream of cruel comments and his inability to admit error or apologize." 

"My conclusion about Mr. Trump’s unsuitability for office is based on his disregard for the precept of treating others with respect, an idea that should transcend politics," Collins wrote.
