Democrat Ron Barber raised more money in the last five weeks than any other Southern Arizona candidate for U.S. House - and it wasn't even close.

In the U.S. Senate race, Democrat Richard Carmona now has the most money still in the bank among the five candidates, pulling slightly ahead of Republican Jeff Flake who had to dig deep into his coffers to defend himself against an aggressive ad campaign from his primary challenger, Wil Cardon.

• In CD2, Barber raised $288,000 from July 3 to Aug. 8, more than six times what his primary opponent in Congressional District 2, state Rep. Matt Heinz, and a would-be opponent in the Nov. 6 general election, Republican Martha McSally. Heinz raised $42,000 while McSally brought in $47,228.

With $377,132 in his campaign coffers, Barber has a big advantage in remaining funds over Heinz and McSally. Heinz is $1,000 in the red after spending $85,400 putting up TV ads, sending out mailers and doing phone banks.

Barber's campaign said the strong fundraising shows Southern Arizona is behind him in his bid for re-election. Heinz said even though he has less money, his campaign is using it efficiently and effectively to close the gap on Barber.

McSally has $127,430 in her campaign account. In her primary, she is facing political newcomer Mark Koskiniemi, who has not filed with the Federal Election Commission because he has raised less than $5,000.

• In the Senate race, Flake brought in nearly $40,000 more than Carmona in the most recent period, which covered July 1 to Aug. 8. But Flake spent $1.5 million, allowing Carmona to take a slight lead in cash on hand.

Carmona is running unopposed in the Democratic primary, and spent only $246,000. He now has $1.75 million in his coffers - $49,000 more than Flake.

Carmona's campaign touted the figures as a testament to the strength of his candidacy and evidence that the former U.S. surgeon general is well-positioned to win in November. Flake's campaign downplayed the gains by Carmona, saying he should have a much bigger advantage considering he's in an unopposed primary.

Flake's opponent in the primary, Cardon, continues to bankroll his campaign with his own money. Cardon raised just $23,500 this period, but loaned himself another $1.32 million. Since he launched his campaign, he's poured in $8.78 million of his own money to keep his campaign afloat. After spending $2 million in July, Cardon has $317,650 on hand.

• In CD1, Democrat Ann Kirkpatrick raised $89,463, adding to her huge advantage over her likely general election opponent, Republican Jonathan Paton, who brought in $51,305 during the period. Kirkpatrick has $826,099 in her campaign coffers - nearly $700,000 more than Paton.

Kirkpatrick's primary opponent, Wenona Benally Baldenegro, has not yet filed her report with the FEC. Paton's main primary opponent, Gaither Martin, raised $7,425 and has $27,857 cash on hand.

• In CD3, Democratic incumbent Raúl Grijalva spent more than twice what he brought in during the period, but still has five times the cash on hand of any of his Democratic or Republican challengers.

Manny Arreguin raised $7,340, and has loaned his campaign $26,000 of his own money since April, records show. He has about $10,900 in cash on hand.

Republican Gabriela Saucedo Mercer reported raising about $8,500 in July and has about $15,600 in cash on hand headed into the primary. She will face Jaime Vasquez, who has not raised enough to be required to file campaign-finance reports.
