Is there no basis in the Senate rules for allowing a declared leave of absence? Unlike BK going AWOL, Barnes announced his absence and has as good a reason as possible (illness). That may be a reason to resign voluntarily or be voted out if one runs for reelection anyway, but surely isn't a reason for being thrown out of the Senate?
I realize this matters little in Barnes's case with the election looming and no move to expel him/"declare the seat vacant", but this is important for future reference.
There was when written a clause excepting declared leaves of absence from counting towards declarations of vacancy. I can't speak as to whether any changes were made subsequently to remove that section.
