Attorney Ben Quayle (R) has raised more than $550,000 since announcing his bid for Arizona's 3rd district House seat. Quayle, the son of former Vice President Dan Quayle, brought in some $90,000 a week since he launched his campaign six weeks ago.

"I am grateful for the overwhelming support for my candidacy," Quayle said in a statement. "People agree that it is time to send the next generation to Washington."

Quayle is one of several Republicans running for the seat being vacated by Rep. John Shadegg (R-Ariz.), who is retiring at the end of his current term.

Paradise Valley Vernon Parker, another contender for the GOP nod, announced last week that he'd raised $230,000 in the first quarter.
