Kentucky Senate candidate Rand Paul (R) raised $1.1 million in the second quarter, according to the Associated Press.

His campaign did not say how much cash was on hand.

The cash on hand number is significant because Paul's primary win was during the second quarter — on May 18th — and candidates usually unleash a flood of money leading up to that vote, particularly when it was a competitive race, leaving little in the bank for the general election campaign.

Paul, the son of Rep. Ron Paul (R-Texas), is a prolific Internet fundraiser and tapped into his father's online support base to raise funds. His $1.1 million total includes $172,000 he raised online Monday, which was his first Internet fundraiser since he became the Republican nominee.

He raised more than $1.2 million in a series of Internet fundraisers throughout the GOP primary. Paul, a darling of the Tea Party movement, became a national figure after winning the primary because of his controversial comments on the Civil Rights Act.

His second quarter haul also includes money from a fundraiser the National Republican Senatorial Committee held for him in Washington last week.

The second quarter fundraising period ended June 30th. Reports are due to the FEC by July 15th.

Paul faces Democrat Jack Conway in the general election. Conway also had a competitive primary, so his cash on hand numbers will be closely examined.
