Overall I think this is a corrupt poll. When you talk to Republicans you get a different sense of things. I am not saying Trump is not out front. I am saying the rest of it is very questionable.
Paying much attention to polling at this point in the race is like celebrating after the first 20 laps of the Daytona 500. Outside of news junkies and people who really pay attention to politics most of the country is not paying much attention.
With that said, one surprising trend that the MSM ignores is that Trump appears to be picking up voters who usually vote or identified as democrat. The main reason appears to be immigration. Will see if the MSM continues to ignore what appears obvious - voters in both parties, including a sizeable number of African Americans, don’t want more immigrants.
