5 Hot-Button Topics Missing From the Debates

— -- Donald Trump has said that he wants policy to be the focus of the presidential debates, but with one of his and Hillary Clinton's face-offs down, along with the vice presidential debate, some notable subjects have been conspicuously absent.

Here are some hot-button issues that haven't been discussed in the tickets' first two debates:

Benghazi

Clinton's role as secretary of state at the time of the 2012 attack on the U.S. consulate in Benghazi, Libya, and the questions that have been regularly and repeatedly raised about her involvement have kept the issue alive for the past four years.

It has been a regular talking point among her critics, but neither Trump nor his running mate, Indiana Gov. Mike Pence, mentioned it.

The Supreme Court

Nearly seven months ago, President Barack Obama nominated Merrick Garland to fill the Supreme Court seat left empty by the death of Justice Antonin Scalia.

Neither his name nor the Supreme Court vacancy came up in either of the debates, and if the Senate continues to run out the clock on the Obama administration, the appointment could be one of the first actions of the next president.

Guantanamo Bay

The promise to close the U.S. detention facility at Guantanamo Bay, Cuba, was a major part of then-Sen. Barack Obama's campaign platform during his 2008 presidential bid, but it hasn't played as big of a role in this race.

At one point during this campaign, Trump said he would be "fine" with putting Americans on trial at the military base, but it has yet to be discussed on the debate stage.

NSA Surveillance

The revelations about National Security Agency data collection from Edward Snowden’s document dump were not been discussed at either debate.

But the latest news of another NSA contractor who allegedly leaked documents could bring the issue to the forefront of the next debate.

Several Social Issues

Same-sex marriage, as well as gay and transgender rights, did not come up in either debate. The legalization of marijuana has also not been addressed.

Abortion is a historically controversial issue, and it has been at points during this campaign. So it has surprised many political observers that the only time it has come up so far was on the vice presidential debate stage, when Pence was asked to cite an instance when he struggled to balance his faith with a policy position.

2 Topics Briefly Touched On

Trump's proposal to temporary bar foreign Muslims from entering the U.S. — which was a major part of his campaign before he rephrased it as "a suggestion" — was mentioned only once, by Democratic Sen. Tim Kaine of Virginia, when he interrupted Pence to mention the issue.

Similarly, there have been no concrete details or descriptions of the candidates' views on how to improve veterans' affairs and the lives of returning service members. The only times it was mentioned came when Kaine accused Trump of not supporting veterans and Pence responded, "Donald Trump supports our veterans."
