Here is why Trump is at fault.
Trump has been starting this campaign to undermine the elections because the polls are telling him he is going to lose. He can't deal with the notion that his presidency is about to be rejected, so he sets up the scenario that the elections are rigged rather than own his failures. He promotes this concept to give him cover for losing the election in November.
The political porn site where you got this ****-a-manie idea published some article to this effect designed to get your gander up; knowing full well how malleable and ill-formed its readers are. (We all noticed, by the way, that you did not provide a cite for this.... the one smart thing you did, because you know you would have been laughed off the stage) You, being played as the useful idiot here, bring this goofy idea to DP expressing your dismay and outrage because you believe it to be true (and, of course, you never thought verify this idea with a credible news source).... and, now all the sane and educated people here have to waste their time helping to correct your twisted thinking on this issue.
Yes, its indeed Trump's fault that his minions are so gullible. Then again, he needs them to be gullible so he can continue to use them for his purpose. He should show some more respect to members of his cult; after all, they love him, he should at least show a little respect back. On the other hand, do the exploiters ever respect their marks?
