It doesn’t help Hillary at all. When the debated comes around someone will ask Trump about this but the steam will all be gone by then. He can reply that he was against the Iraq war and his opponent, Hillary, voted for it. Boom!
Maybe you’re not watching the polling or maybe you’re not watching what the media is focused on. Trump gave them the welcome opportunity to talk about something other than Hillary’s emails and lies and scandals. Trump allowed this to happen. Instead of talking about the lies, the emails and the scandals, the public is talking about Khan. Not good. This was an unforced error and I hope Trump learns something from Pence. Let Pence deal with the idiots. Trump should focus on one thing and one thing only: Hillary.
