Henry Cuellar was for the Trafficking Victims Protection Act before he was against it. Seven years ago the bill passed almost unanimously in the House, with Cuellar voting for it. Fast forward to 2014 and Cuellar wants to change the bill to deport children from Central America as quickly as possible, no matter what circumstances the children are facing at home.
Cuellar's efforts are hailed as bipartisan but nobody on the left is siding with him on this issue. It's basically every republican and Henry Cuellar that's looking to change the law. That's hardly bipartisan. Henry Cuellar is up for re-election in a red state, and in a district that is looking closely at the events that have transpired on the border in recent months. He's playing to the conservative base, basically, and perhaps is thinking that the GOP will have major gains in the November election. He's acting out so people will notice, and thus, send him back to Washington.
Henry Cuellar will vote with whichever party as long as it's a benefit for him.
