Pennsylvania: Mary Landrieu

From The Hill:
Senate Democrats on Wednesday banded together to defeat — barely — a Republican proposal to allow concealed weapons to be carried across state lines.

Voting 58-39, the chamber beat back an amendment by Sen. John Thune (R-S.D.), a potential presidential hopeful who has taken on a growing role among Senate Republicans, that would have permitted weapons to be transferred from state to state.

Under a previous agreement between the two parties, the amendment needed 60 votes to pass.
