Less than 12 hours into Rand Paul‘s one-day Tea Party “money bomb” fundraising event, the Kentucky Senate candidate had already surpassed the $100,000 mark, according to the real-time donation counter on Paul’s Web page.

That total puts Paul, the son of libertarian champion Rep. Ron Paul (R-Texas) at over $400,000 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 over $430,000 from a money bomb event in August.
