Mitt Romney fundraising jumps after V.P. roll out

(CNN) -- Following the roll out of his vice presidential pick, Mitt Romney's fundraising numbers got a Republican enthusiasm-fueled boost.

On Sunday, Andrea Saul, Romney's campaign press secretary, wrote on Twitter that fund-raising had spiked for the candidate after revealing Paul Ryan as his running mate.

"$3.5 million raised online in 24 hrs of @MittRomney's pick of @PaulRyanVP #RomneyRyan2012"

That was a jump from midday Saturday, when Saul wrote that Romney had brought in just over $1 million since Ryan's name went public.

"HERE FIRST: @MittRomney has raised over $1.2 million since pick of @PaulRyanVP #LessThan4Hours"

Later Saturday afternoon, Saul tweeted again updating the Romney campaign fundraising numbers to just over $2 million.

"Just passed $2 million raised since @MittRomney announced @PaulRyanVP #RomneyRyan2012"

In July, Romney's campaign and the Republican National Committee raised $101.3 million - an average of $3.4 million per day, raised mostly through high-dollar fund-raisers.

Together, the RNC and Romney's campaign ended July with $185.9 million cash on hand. The Republican effort had $160 million in the campaign war chest at the end of June. Both months' numbers include money raised by Romney's campaign, the Republican National Committee, and several state parties in a joint committee known as Romney Victory.

Compare the Romney fundraising numbers to those of Obama and the Democratic National Committee's July haul of $75 million and $71 million in June. Last month marked the third consecutive month the president was outraised by Romney.

Romney's campaign weren't the only ones fund-raising off the Ryan announcement, however. Following Romney's vice presidential announcement, senior adviser David Axelrod emailed supporters touting a new web video attacking the newly formed pair and asking folks to 'chip in.'
