Republican Rand Paul held his fifth and, his campaign said, final online money bomb fundraiser, bringing in more than $101,000 in 24 hours.
Although breaking six figures, the fundraiser brought in quite a bit less than similar events staged by Pauls campaign to win the GOP Senate nomination.
Paul is competing against Secretary of State Trey Grayson in the Republican primary.
He has been running ahead in public polling but behind in fundraising.
As of April 1, Grayson had more than $1 million in the bank compared with nearly $400,000 banked by Pauls campaign.
At this point, most of the candidates money will go toward funding the all-important air war in the final weeks of the campaign. Pauls camp noted that the April 1 cash totals came after spending nearly $575,000 to reserve airtime during the final six weeks of the campaign.
The bottom line is weve got a pile of money, and by May 18 well have spent all of it effectively enough to win the race, campaign manager David Adams said.
