UPDATED: Thune amendment fails; falls two votes short

A controversial change to gun control policy fell two votes short of Senate passage this afternoon.

The “Thune Amendment”–named after chief sponsor Sen. John Thune (R-S.D.)–would have forced states that grant concealed firearm permits to honor such permits from other states.

Opponents argued that states have much different standards for getting a permit, meaning states with stricter standards would have to honor permits from state’s with a more lax policy.

The amendment garnered 58 votes, including 20 Democrats. Two Republicans–Sens. Richard Lugar (R-Ind.) and George Voinovich (R-Ohio) voted no. Under Senate rules, the amendment needed 60 votes.

UPDATE: The following Democrats voted for the amendment:

Baucus (D-MT)
