It's the time of the year when congressional candidates start crowing about the amount of money they raised in the second fundraising quarter of the year.

The first one we've heard from is U.S. Rep. Ron Barber, who told the press today he'd raised more than $550,000 between April 1 and June 30 for his reelection effort in Southern Arizona's Congressional District 2. Barber ended the quarter with more than $1.5 million in bank, according to Team Barber spokeswoman Ashley Nash-Hahn.

That's the biggest haul for Barber in a single quarter for the 2014 cycle. The incumbent Democrat had trailed his likely GOP opponent, Martha McSally, in the previous three fundraising periods.

Nash-Hahn took a took shot at McSally in the press release announcing the numbers.

"While Martha McSally hobnobs with East Coast billionaires and Wall Street’s favorite congressman, Eric Cantor, Ron is fighting for our families," Nash-Hahn said. "Our community sees beyond Martha’s empty campaign slogans and slick ads for what she really is—an extremist who wants to cut Medicare, raise taxes on middle class families and eliminate the minimum wage."

In other CD2 news, Roll Call reports that both sides are reserving more TV time in the fall:

Ret. Air Force Col. Martha McSally, a Republican challenging Democratic Rep. Ron Barber, placed television reservations in the Tucson media market for the final weeks of the 2nd District race, according to a campaign source.

The total sum of the McSally buy is $460,000 on broadcast and cable in the relatively inexpensive market.

Additionally, House Majority PAC, a Democrat-aligned super PAC, is upping its own reservation in the district from $140,000 to $440,000, according to a Democratic source watching the Tucson media market.
