No.
Trump is stuck at 38-43%. HE HAS NOT MOVED BEYOND THOSE NUMBERS FOR THREE MONTHS.
Hillary's been above 50 and is now around 40-44. So, it's Hillary who is losing, due to the email scandal and the trust factor.
Trump is not gaining. He cannot help himself; he'll go off script at some point, again, and remind voters that, the reservations they had about him in the first place, were well placed.
The election is still about Trump and that means he loses.
