You can learn a lot about a politician by studying his tax returns. In John Kerry's case, one thing you can quickly figure out is what years his name actually appears on the ballot. If it's an election year, he makes charitable contributions. Last week, for example, he claimed $43,735 in charitable donations for 2003, more than he'd given in the prior two years combined.
In 1990, running for reelection to the Senate, he donated $1,835 to charity. After winning, he ponied up a total of $975 in the next three years.
