Teresa Heinz Kerry gives millions of dollars to many groups. She is considered one of the most prolific philanthropists in the United States and I am sure she can be "linked" to numerous groups on both the left and the right. Her politics are very middle of the road, and she was a Republican for most of her life.
All this being said, the NY Post has every right to publish this story, it just loses much of its punch when it is reported in such a partisan way. (This is true of the NY Times on the flipside - so save me the Liberal Media comments).
By the way, if you are interested here is a like to the Tides Foundation web-site:
