Politico: “As the Florida Republican has catapulted to the top tier of the crowded GOP presidential field, Rubio has been absent more often than other senators seeking the White House. Since announcing his run in mid-April, Rubio has missed 42 votes, more than a third of roll calls on the Senate floor. Trailing not far behind him on the absentee scale are Sens. Lindsey Graham (R-S.C.) and Ted Cruz (R-Texas). At the other end of the spectrum is Rand Paul of Kentucky, who has missed just two votes.”
