rassy seems to be the most political biased mainstream pollster of the USA.
la times is strange idd.
idb/ipp seems worrisome..... cause, if 3 trackers see a wholy different picture than the rest, one could wonder...why?
Rasmussen uses robo-call so it leans Republican.
LA Times uses a sample based on whom people voted for in 2012 to draw an electorate share. People have winner's bias so it's likely not accurate.
IDB/TIPP is interesting to me because even though they usually have a slight Republican bias they have been reasonable. They were great in 2004 and 2008 but were off by 2.3 in favor of Romney in 2012 so there is some chance they're continuing to slide away further from being an accurate poll.
But they could turn out to be a genius and shock us all.
