I'm tired of rich liberals saying I should pay more taxes so Barack Obama has more money to spend. If they feel so strongly about giving more of their income to the government, there's nothing stopping them from doing it other than their own hypocrisy. Put your money where your mouth is.

From the Treasury Department website:

How do I make a contribution to the U.S. government?

Citizens who wish to make a general donation to the U.S. government may send contributions to a specific account called "Gifts to the United States." This account was established in 1843 to accept gifts, such as bequests, from individuals wishing to express their patriotism to the United States. Money deposited into this account is for general use by the federal government and can be available for budget needs. These contributions are considered an unconditional gift to the government. Financial gifts can be made by check or money order payable to the United States Treasury and mailed to the address below.
