The presumptive Republican nominee raised $101.3 million combined between his campaign and the Republican National Committee, the Romney camp said in a statement.
Romney and the RNC now have around $185.9 million of cash on hand to throw into campaign advertising and grassroots get-out-the-vote efforts in the intense final months of the campaign to deny Obama re-election in November.
Obama has yet to reveal corresponding figures for July, though previous numbers show the once champion fundraiser being seriously outgunned by Romney.
July’s figure was slightly down from Romney’s record take of $106.1 million in June, which dwarfed Obama’s haul of $71 million for the same month.
Romney is also getting a deluge of support from SuperPac campaign committees into which individuals and corporations can pour unlimited sums into attacks on the president and his record.
The Republican’s camp said that 94 percent of all his donations received in July were for $250 or less, seeking to counter perceptions fanned by the Obama campaign that he is overwhelmingly funded by rich donors.
“Once again we see that for many people, this is more than a campaign, it is a cause,” Romney Victory national finance chairman Spencer Zwick and RNC Chairman Reince Priebus said in a statement.
Obama campaign chiefs have tried to drum up more enthusiasm among Democrats for fundraising, warning several times that they are likely to be beaten by Romney and that a large gap in resources could be decisive.
The president has a string of fundraisers planned, including one at his family home on Sunday in Chicago.
