Giuliani spent $11.2 million in the second quarter.

WASHINGTON (CNN) – Republican presidential hopeful Rudy Giuliani spent $11.2 million for his White House bid in the second quarter of 2007, compared to the $15 million he raised for the primary in the same period, his campaign announced Thursday.

Giuliani’s rate of spending, or “burn rate,” more than doubled from 34 percent in the first quarter to 75 percent in the second quarter, largely due to an effort to set up field operations beyond the early states of Iowa and New Hampshire. The campaign’s overall burn rate for 2007 is 59 percent.

According to Giuliani campaign manager Mike DuHaime, the campaign now has field operations set up in a dozen states, including the delegate-rich states of Florida and California, which will hold their primaries earlier than ever before.

“It’s very important that we do a good job with the money that’s entrusted to us from people all over the country,” said DuHaime in a conference call with reporters. “Even though we are growing right now, we are running a very efficient campaign.”

The campaign also announced that it raised $1.3 million in Internet donations during the first half of the year. At the end of March, the campaign had said it raised “nearly $1 million” since first setting up a campaign committee in December 2006.

All presidential candidates have until July 15 to submit detailed fundraising and spending reports to the Federal Election Commission.
