The Democrats are making an issue of Mitt Romney’s wealth. For example, David Letterman, who makes $50 million per year, went on the attack last week. Letterman is worth $400 million while Forbes estimates that Mitt Romney is worth $230 million.

Bashing Romney for his wealth has not stopped President Obama from going to the multi-millionaire well to bolster his campaign coffers. George Clooney, who hosted a fund raiser right after President Obama said he supported “Gay Marriage,” is worth $160 million.

“On the same day his campaign launched an attack on Mitt Romney‘s record in private equity, President Obama” attended “a big-dollar fundraiser at the Manhattan home of Hamilton ‘Tony’ James. . . . Many in attendance . . . have ties to the private equity sector.”

Tom Hanks, a big Obama supporter, is worth $350 million. He and his liberal wife live in a $26 million Pacific Palisades mansion.

Where were the rich-money critics when John Kerry was running for President? Kerry married Teresa Heinz, the widow of Pennsylvania Senator H. John Heinz III. As far back as 2004, the Los Angeles Times put Teresa Heinz’s wealth at between $900 million and $3.2 billion. Even without his wife’s inherited money, Kerry is wealthy in his own name, being the beneficiary of at least four trusts inherited from Forbes family members, including his mother, who died in 2002. Kerry, a Democrat, is one of the wealthiest U.S. Senators.

Here’s a list of some of the richest Democrats in Congress and their ranking in terms of their maximum net worth:

3. Jane Harman (D-Calif): $493,604,000

4. Mark Warner (D-Va): $309,088,999

5. John Kerry (D-Mass): $281,976,067.

6. Herb Kohl (D-Wis): $258,847,994

7. Jared Polis (D-Colo): $228,492,998

9. Nancy Pelosi (D-Calif): $196,299,990

10. Jay Rockefeller (D-WVa): $136,482,003

12. Frank R. Lautenberg (D-NJ): $116,071,021

13. Dianne Feinstein (D-Calif): $93,707,020

14. Richard Blumenthal (D-Conn): $91,183,450

I don’t resent or envy people who are rich, but I do resent the hypocrisy of liberal rich folks who denigrate prosperous conservatives and use their wealth as a campaign issue.
