The why are Trump's numbers dropping in the southeastern states he's already won?
Who knows? Irrelevant cause he’s won them.
Just try surveying people here on FR. I know several, who have posted here recently, who have converted. It will get worse for Ted, better for Trump.
BTW, last two Reuters polls, Trump has increased his total now to over 43 and two days ago was over 45. Yep, losing support.
