The speechwriter for "Benghazi mom" Patricia Smith at the GOP convention may defect to vote for Hillary Clinton in November.

Smith is the mother of an American killed in a 2012 terrorist attack in Benghazi, Libya, which happened during Clinton's tenure as secretary of state.

Richard J. Cross III penned an op-ed in the Baltimore Sun that explained how the self-described "longtime Maryland Republican" may dump Donald Trump on Election Day.

"I personally drafted the speech of the 'Benghazi mom,' Patricia Smith. In that speech, I concluded with the following line: 'If Hillary Clinton can't give us the truth, why should we give her the presidency?' As a political speechwriter, that was something of a home run moment for me," Cross wrote. "But weeks after the end of the 2016 GOP convention, I am confronted by an inconvenient fact: Despite what I wrote in that nationally televised speech about Hillary Clinton, I may yet have to vote for her because of the epic deficiencies of my own party's nominee."

Cross wrote that he has never voted for a Democrat for federal office, but he found no cause to disagree with President Obama's criticism of the GOP nominee.

"I cannot vote for Donald Trump. I could never vote for Donald Trump," Cross wrote. "So instead I am confronted by two painful choices: vote for the most divisive political figure in the past 25 years or throw away my vote on a kooky Libertarian ticket."

He continued, "[T]he prospect of voting for Hillary Clinton is uncomfortable to me, as if Dr. Van Helsing were compelled to vote for Dracula. But the only prospect more terrifying than voting for Hillary Clinton is not voting for her. The reality of American politics today is, she is the only choice."

Cross, who described Richard Nixon and Ronald Reagan as his childhood icons, said he did "recognize" his party under Trump's rule. Cross' predicament is representative of the type of Never Trump voters that the GOP nominee could need to win over to take back the White House in the fall.
