That’s because you are not thinking.
The picture tells you Trump has A LOT of support.
Political Campaign Experts say less than 1% of a candidate’s supporters actually show up to a political rally. Therefore, if you want to know who the voters support, then just look at a Candidates crowd. Not at just one rally but all the rallies combined.
Thus, in a free society whoever has the biggest numbers at a rally is the candidate that has the most support. Provided it’s a fair and free election vs. a rigged and fixed election.
I saw a lot of pictures in 2008 that showed Obama had a lot of support. That doesn’t mean he was a good candidate TO support.
