Rep. Ron Paul (R-Texas) on Monday released a fundraising appeal asking his supporters to participate in an online “money bomb— fundraiser Wednesday to benefit his son’s Senate campaign in Kentucky.

“In 2007, we made history together by raising over $6 million in one day,— wrote Ron Paul, who ran for president in 2008. “Now, we need to make this December 16th special by helping propel my son, Rand, to the United States Senate. Our fellow lovers of Liberty are organizing a Money Bomb for Rand and we need your help.—

So far this year, Rand Paul, an eye surgeon, has made good use of the national Internet-based fundraising and libertarian network that his father built last cycle. Part of the reason that Paul is considered a serious threat to Kentucky Secretary of State Trey Grayson — the establishment choice in the GOP primary — is because he raised an impressive $1 million in the third quarter.

“Sending Rand to Washington would be the greatest victory for limited government and the Constitution we have seen in years,— Ron Paul wrote. “Rand’s election will send a message to the establishment that we are taking our country back and the pave the way for future success together.—

As of Monday, Paul had already raised more than $300,000 during the fourth quarter.

Unlike Paul, Grayson waits until the end of the quarter to release his fundraising totals. Grayson raised $643,000 from July through September.
