Yes the gray is the margin of error.

What is good is Trump is getting out of the MOE but so is PIAPS

If she drops .3 she out of the gray as well

MOE of a particular sort. MOE is most often applied to a single "mean" value. For xample, in this poll, the "mean" for Trump is 47.0%, and that single value has a margin of error.

The grey band accounts for MOE of two samples (two MOE's, if you will), and aims to describe the probability that the item with the higher sample average, actually has the higher value in the whole population.
