A little more clicking on the opensecrets.org will reveal the individual donors involved in each contribution. If you look for the source of the Cruz donations, you will find that they come from Robert Mercer, not James Simons as claimed in the article:

Meanwhile, the contributions to the Clinton campaign came from two completely different individuals, Henry and Marsha Laufer from Lantana, FL (whoever THEY are):

The only thing in common between these two is that they list the same employer.
Please pay attention to the following post on the opensecrets.org website:
The money came from the organizations' PACs; their individual members, employees or owners; and those individuals' immediate families. At the federal level, the organizations themselves did not donate, as they are prohibited by law from doing so.
and try not to make such utter FOOLS of yourselves in the future.
