The problem is Trump wasn't wrong.
Even CNN reported on-air Alabama was in danger. NOAA admitted that when the President made the statement Alabama was projected to be hit. Then there is the fact Mobile, Alabama is about 60 miles from Florida, and we are talking about a storm that was roughly 1,000 miles in diameter. Any part of Florida being hit necessarily means Alabama will be hit as well.
It's just pathetic that you are so easily controlled that you believe Trump was wrong simply because some idiots in the MSM told you Trump was wrong.
