I mean, on the heels of the Hsu problem, now there is another dirty donor to the Clinton campaign.

Sant S. Chatwal, an Indian American businessman, has helped raise hundreds of thousands of dollars for Sen. Hillary Rodham Clinton's campaigns, even as he battled governments on two continents to escape bankruptcy and millions of dollars in tax liens.

The founder of the Bombay Palace restaurant chain, Chatwal is one of a growing number of fundraisers in the 2008 presidential campaign whose backgrounds have prompted questions about how much screening the candidates devote to their "bundlers" while they press to raise record amounts.

Chatwal's case reached from his native India to New York City. The IRS pursued him for approximately $4 million in unpaid business taxes, while New York state placed a lien seeking more than $5 million in taxes. He forfeited a building to New York City on which he was delinquent on property taxes and was sued by federal regulators seeking to recoup millions of dollars in loans from a failed bank where he served as a director.

Across the ocean, three Indian banks forced him into U.S. bankruptcy, and he was charged with bank fraud. He was out on bond when he showed up in India in 2001 during a visit by his longtime friend Bill Clinton.

Yet none of the legal and financial woes -- occasionally touched on in American or Indian newspapers or highlighted by political opponents -- raised red flags inside Hillary Clinton's fundraising operation. Chatwal recently said he plans to help raise $5 million from Indian Americans for Clinton's presidential bid.

But none of this caused any concern to the Clinton campaign. I guess they just have low standards -- or maybe, like Hsu, Chatwal was really trying to buy a Marc Rich-style pardon and the Clintons knew it.

Of course, John Edwards has had problems, too.

Former senator John Edwards (D-N.C.) faced such questions last week when federal prosecutors in Michigan indicted Geoffrey Fieger, the lawyer famous for defending assisted-suicide advocate Jack Kevorkian, accusing him of channeling $127,000 in illegal contributions into Edwards's 2004 presidential campaign. Edwards's aides said, and prosecutors confirmed, that the activity was concealed from Edwards and that the candidate cooperated once he learned of problems.

As has Obama.

Similarly, Sen. Barack Obama (D-Ill.) gave to charity more than $30,000 in donations from Illinois fundraiser Antoin "Tony" Rezko and his associates after Rezko was indicted in a federal corruption case. "We do our best to go through the hundreds of thousands of people who give to make sure there aren't problems," Obama spokesman Bill Burton said. "I wouldn't say it's a perfect process, but we are as vigilant as possible."

But the bulk of the dirty money seems to be headed to Hillary. Could this be a case of (jail)birds of a feather flocking together?
