WASHINGTON, July 17 (UPI) -- Sen. Barack Obama's presidential campaign raised $52 million in June, more than double what it raised in May, his staff announced Thursday.
The sum is about $30 million more than Sen. John McCain, R-Ariz., said his campaign raised in the same month, The New York Times reported.
"This campaign is in a very strong financial position," Obama's campaign manager David Plouffe said in a letter to supporters.
But, Pouffe noted McCain and the Republican National Committee had nearly $100 million to spend, compared with Obama's campaign, which had a total of $72 million.
The Illinois Democrat also has a fundraising challenge ahead of him, since he announced he would not accept public financing, the Times reported.
Contributions to Obama's campaign in June averaged $68 per donor, Plouffe said.
