Lindsey Graham may have been approaching zero in the polls when he bowed out of the race for the Republican nomination Monday, but his exit, and the aftermath, are noteworthy for a few reasons.

First, Graham leaves the presidential field without a candidate who has served in the armed forces. (Leaving out Army vet Jim Gilmore, who hasn’t met the debate requirements for months.) Former Texas governor Rick Perry was the only other major candidate to have served, and Graham’s departure is a stark reminder that there’s no military experience left in either party’s slate of candidates to be commander in chief.
