The 4 Democrats who voted for the filibuster on the (already largely ineffectual) background checks on guns need to have their political careers ended:

As the Senate began voting Wednesday on nine proposed changes to a gun control bill, the centerpiece proposal on background checks quickly failed to win enough support, despite broad public backing.

The vote on the so-called Manchin-Toomey amendment was 54 in favor, 46 against — failing to reach the 60-vote threshold needed to move ahead. Four Republicans supported it, and four Democrats voted no.

………

In addition to McCain and Toomey, the amendment was supported by Republican Sens. Susan Collins (Maine) and Mark Kirk (Ill.) The Democrats who opposed the measure were Sens. Max Baucus (Mont.), Mark Begich (Alaska), Heidi Heitkamp (N.D.) and Mark Pryor (Ark.) The four Democrats face difficult reelections in rural states with strong gun cultures.

And their votes will not make a difference.

The NRA will still run ads against them, and the 10% of the electorate who oppose a sane background check policy would never vote for them.

It is more important to enforce meaningful party loyalty than it is to allow these ratf%$#s to hold their seats.
