Money Down the Drain
Everyone - including the GOP - knows that the Wall is a bunch of baloney, and that it would be scandalous to divert military funding to the president’s vanity project from actual, serious, strategic objectives. The truth is that the situation at the border is better than it’s ever been, with illegal crossings at an all-time low in 2017, down by 80% from 2000.
If your representatives are Republican, contact them and express your concern that important military objectives will be set aside in order to fund the president’s vanity project. If they’re Democrat, you should still let them know you want to stop any funding diversion for the Wall.
