I guess some did not get the memo.. You wear red to the polls to show a vote for Trump. Then the crooked media can’t screw with the exit polls.
If half of Trump voters wear red (a vast overestimate of the number who might), and Trump takes 60% of the vote (a possible but optimistic number if his hidden support is as large as imaginable), that's still not enough. That would be 30% of voters wearing red, 70% not wearing red. That will not prove vote fraud or exit poll bias.
Wearing red is a nice gesture, but I'm a conservative; I believe in action over symbolism. I'd rather have actual boots on the ground as poll watchers. I'd rather have Trump's people getting extra patriotic voters to the polls to balance out the fictional and dead voters Hillary's people will be bringing. We need an all of the above strategy. As O'Keefe has proven, that is what Hillary's thugs will be doing.
