LOS ANGELES, CA (Catholic Online) - The Obama camp is aggressively pursuing wealthy and smaller-dollar donors alike to pitch in. Democrats have trailed behind Romney and the Republican National Committee by $35 million in June and about $17 million in May.

Email missives have been aimed at working-class donors, and Obama himself has been asking his 2008 big donors for more cash. The search for new donors is a major priority.

"There is a sense of urgency that things are going well but we need to redouble our efforts," Don Peebles, a Washington real estate developer says. Peebles sits on Obama's national finance committee and is credited with bundling as much as $200,000 for the reelection campaign.

Peebles said there are "constant phone calls and discussions" among finance committee members which have encouraged bundlers to pick up the pace. "Trying to find new big donors, that are one of the big things," he said.

Peebles says that Obama has alienated potential big donors with attacks on Wall Street. In the meantime, his reelection campaign has already reaped the maximum contributions from its most supportive big donors.

The challenge ahead for Obama bundlers is identifying and courting new donors "because the donors who are predisposed to give to him have already given," Peebles says.

Some Democrats have expressed concern that the presidential cash race may have reached a tipping point. While GOP super PACs have been outraising their Democratic counterparts for months, Democrats have taken solace in Obama's ability to bring in heaps more campaign cash.

If Romney and the Republicans keep their current activities at the current pitch, Democrats could fall far behind in the race on both fronts.

The Obama campaign sent emails this week pleading for more cash, even after chalking up its best fundraising month of this campaign in June.

"We could lose if this continues," warned the email sent by the Obama campaign to supporters.

"We had our best fundraising month yet, and we still fell about $35 million short. We can win while being outspent - but we need to keep it close," said the email from Ann Marie Habershaw, the campaign's chief operating officer.

The email asks for $3 or more to help close the gap. "If we can't keep the money race close, it becomes that much harder to win in November," she warned.
