The notion that MSM polls are "scientific" and "non-political" is laughable. These are the same pollsters that omitted Bernie Sanders from the primary polls and then omitted the Green and Libertarian Parties in almost every poll conducted during the actual election season. That obvious bias towards the two-Party duopoly denied Americans an ACTUAL debate on actual issues and instead gave us a freak show where we were told we had to hold our noses and vote for the candidate we hated the least, because the two 3rd Party Candidates didn't poll on at 5% on the polls they weren't even included on!
That's what really sucks about Trump when it comes to what he says about MSM polling. The man lies 97% of the time, but when he actually speaks the truth, we feel compelled to come to the defense of the liars he just called out - you know, because Trump lies 97% of the time.
