That is true, but the wind/rain/flooding etc will put damper on their travels for a few days, if it slows them down till after the election, that would be a positive for President Trump
No, it will not. The hurricane track is over a thousand miles away from the caravan.
After all, this is purely a pre-arranged political stunt, arranged to come to a head immediately before the election. This is not a coincidence at all.
An unexpected force, like a hurricane, delayed it until after the election, it would mean the PR stunt was a failure. Mexico, who is complicit in this, would simply pull the plug on the venture, and round up the stragglers and ship them back. We would never hear of it again.
