The last two days polls have been sub-optimal for Trump as he declined in PPD from +1.4 to +0.6, a sharp drop in USC/LATimes from +0.3 to minus 1.3 and a two point drop in IBD to a tie.
USC has shown these sharp fluctuations before and the next few polls across these five trackers will be instructive.
IBD is a concern as it is rated the most accurate and whilst Rasmussen has held up at Trump +2 the general trend over the last few days has been negative. That said the aggregate is still basically a tie with Clinton at a tiny
+0.3 point lead.
Over time Clinton has declined in the aggregate of the four original polls excluding IBD from her high on 10/11 of +3.7 to +0.4 today
