So now you're claiming that the only reason why Jim Simons donates is to evade taxes?
And, the man who had day-to-day operational control of RenTech after Simons retired in 2010 was ~noted Democrat donor~ Bob Mercer.
~noted Republican donor~ you mean.

Apologies if my attempt at sarcasm fell flat. I was assuming the author of the parent comment knew that Mercer was associated with Cambridge Analytica and Trump. Judging from his follow up, he seems to have picked up on the sarcasm.
