Note that of the top 20 donors over a 20 year span, a mere 2 slightly favor Republicans, while only 4 are relatively neutral (though two lean slightly Democrat and two lean Republican). The remaining 14 of the top 20 political donors are solidly in the Democrat camp.
The full list of the 140 top donors can be found at the link.
