Mitt Romney’s selection of Rep. Paul RyanPaul Davis RyanEmbattled Juul seeks allies in Washington Ex-Parkland students criticize Kellyanne Conway Latina leaders: 'It's a women's world more than anything' MORE (R-Wis.) as his running mate has energized donors, with the campaign raising $3.5 million in the 24 hours since the announcement.

Campaign spokesperson Andrea Saul tweeted the fundraising haul on Sunday.

Yesterday, Saul provided updates at the Romney campaign saw a spike in donations after Ryan was named to the GOP ticket. A tweet Saturday afternoon said that $1.2 million had been raised within four hours, with $2 million total by the end of the day.


The campaign was quick to fundraise off the seven-term Wisconsin lawmaker, who is a popular figure with the conservative base. 

An email sent shortly after Romney welcomed Ryan at a campaign event in Norfolk, Va., asked supporters to “Donate $15 today to help restore America's greatness and build a stronger middle class.”

On Sunday, the campaign sent a fundraising pitch from Ryan telling supporters he was “thrilled” and “deeply honored” to be Romney’s running mate. 

The email told backers they could win a chance to meet him and Romney and encouraged them to donate before Wednesday to enter a raffle. 

Democrats as well are using the Republican VP pick to fill their campaign coffers. An email from Obama’s campaign yesterday said that with Ryan’s selection, Romney had “doubled down on his commitment to take our country back to the failed policies of the past,” and urged supporters to donate. 

“Election Day is closer than you think — make a donation to fund this campaign in the time we have left,” the email said.

Ryan’s boost to Romney’s war chest comes after the GOP candidate and RNC out-raised Obama and Democrats for three straight months.

In July, the Romney campaign and RNC’s joint efforts netted a a $101.2 million haul, over $27 million more than Obama campaign and Democratic National Committee’s (DNC) $74 million.

It was the second straight month that Romney had passed the $100 million mark, intensifying concerns on the Obama campaign that they may be outspent in the run up to election day.
