PHOENIX -- Republican Senate candidate Jeff Flake released his latest fundraising totals Friday and they show him trailing his potential Democratic rival.
Flake hauled in about $908,000 during the second quarter, according to a statement from his campaign officials. The totals were less than the presumptive Democratic nominee, Richard Carmona, who reported raising about $1.1 million over the same time.
Other than the statement, Flake's campaign wasn't commenting on the numbers. Flake, who has served six terms in Congress, has about $2.76 million in his campaign coffers. That number is better than the $1.6 million Carmona has.
Flake's well-funded Republican primary opponent, Wil Cardon, has not said what he raised, yet. But Cardon, who is a businessman, has tapped his personal fortune to finance his campaign so far.
The two Republicans have been trading political shots in recent television spots that started airing this week. Flake accused Cardon of hiring illegal immigrants in one ad.
On the other hand, Cardon produced his own commercial showing Flake saying he lied about his promise to voters to only serve three terms. The back and forth has many Republicans worried the tough primary will hurt the party's chances in the November general election.
One of those Republicans was Sen. John McCain, the 2008 Republican presidential nominee who said Friday, "frankly I also worry these attacks might make it harder in the general election for us the elect Jeff Flake to the United State's Senate."
McCain made his comments after he and retiring Sen. Jon Kyl endorsed Flake in the Aug. 28 primary.
Kyl announced that he's leaving office after his current term ends.
