I hope the swamp can be drained but I'm not going to hold my breath. Right now it looks like the swamp swallowed up Trump, as he is appointing neocons to key positions even though he campaigned against the neocon foreign policy of pursuing military action throughout the Middle East. The worse example is his recent appointment of John Bolton to be his National Security Advisor. This tweet has not aged well at all.
Trump also failed to get funding for the Border Wall, his signature campaign promise. If the Republicans lose control of the House of Representatives in November, which is looking increasingly likely, the wall may never get built.
