So, Hillary announced that she'll campaign with him to give him a "boost" and he's already dropping in support ... 
According to DKE (link), St. Pete Polls' last result was Gillum+1, conducted September 5th - 6th. So technically this would be an improvement.
But it's also such a small change that it is indistinguishable from noise.
LOL at Tender. Looks like the Hillary Bounce has caused Gillum to double his lead!
But seriously Tender, not everyone is as obsessed with Hillary as you. 99% of the state probably doesn't even know about it.
