JFK is just one of many rotten Crats, but we really shouldn't misstate his record of tax-deductible donations.
According to the National Review (
http://www.nationalreview.com/york/york200403220840.asp) he contributed only small amounts up to 1995. (1991, $0; 1992, $820; 1993, $175; 1994, $2039; 1995, $0.) From 1991 to 1995, Kerry "earned" about $625,000 and donated about one-half of 1%.
At first thought, you'd think that the Kennedy clan would gotten him to kick in more than to Special Olympics alone. But, look, Teddy knows that dating rich and famous babes cost serious bucks and don't leave anything for the needy.
Now that he's married to the Heinz heiress, Kerry no longer has to pick up the check. So, he has boosted his charitable contributions to the 10-13% range, based on his income alone. (1996, $14,325; 1997, $21,795; 1998-2001, unknown; 2002, $18,600)
But, it's still chump change. Forbes puts the Heinz fortune at $525 million; at a very conservative 5% return, that translates to around $25 million of income per year. Teresa Heinz evidently files separately, so I don't know how much she contributes.
In comparision, GWB contribute over $300,000 in a single year.
