It's one thing to express and/or support a political view that others may disagree with, within the accepted bounds of our democratic process. (You can disagree with the viewpoint, but the act of making the donatio itself isn't illegal or immoral.)

It's another thing to subvert our system of government via deception, surveillance and/or intimidation, either by taking action outside the bounds of legal limits, or working to redefine those limits to suit your own purposes. There's a fair argument that these two situations are not comparable, regardless of how you feel about Eich's donation.
