As of close of business Wednesday, Kentucky Senate candidate Rand Paul (R) had raised at least $170,000 through his one-day online “tea party money bomb,— according to the real-time donation counter on Paul’s Web page.

That total puts Paul, the son of libertarian champ Rep. Ron Paul (R-Texas), at more than $470,000 raised during the fourth quarter.

Wednesday’s money bomb event was scheduled on the 236th anniversary of the Boston Tea Party.

Paul’s Internet-based money bomb events have become the fundraising bedrock of his primary campaign against Kentucky Secretary of State Trey Grayson (R), the establishment choice in the race.

Paul netted nearly $190,000 from a money bomb event in September and more than $430,000 from a money bomb event in August.
