In 2002, when I began covering Export-Import Bank votes, the GOP-controlled Senate reauthorized the agency by voice vote. In 2006, they did the same.
In 2012, there was actually a roll call vote, and 19 Republicans voted "No" — including party leader Mitch McConnell, R-Ky.
This year, 28 Republicans voted against reauthorizing Ex-Im. Of the four Republican senators who missed the vote, three are Ex-Im opponents: Sens. Jeff Flake, Bob Corker and Marco Rubio.
If you put Missouri Sen. Roy Blunt on the "Yea" side (where he has historically been), that leaves the GOP conference at 31-23 against Ex-Im. That's not merely a majority of the majority, that vote breaks down to 57.4 percent to 42.6 percent — a blowout.
*The chart above counts Sen. Mark Kirk in 2012 as supporting Ex-Im, which he vociferously does, although he missed the vote after his stroke. It also counts Flake, Corker, and Rubio as opponents in 2015, and Blunt as a supporter in 2015.
