Wait a minute ... 38 to 38? That means only 76 senators were present to vote? What happened to the 22 other senators? (105 senators in a full Senate, but 7 seats currently vacant, according to WIKI)

Some pundits have called for mandatory voting for eligible voters. Maybe that should be extended to the members of both the HoC and the Senate. No vote? Pay a hefty fine. Absent without just cause? Same thing.
