Former Republican congressman J.D. Hayworth is launching a robocall campaign in Arizona prior to the formal announcement of his Senate candidacy. The call, which the Hayworth campaign says is going out to "tens of thousands of Republicans statewide," takes direct shots at Sen. John McCain (R-Ariz.) for his length of service and voting record.

Here is the script, as provided by Hayworth:

Hi, this is JD Hayworth calling. If you share my opinion that John McCain has admirably served our country but that 28 years in Washington is just too long, then I want you to know that I will soon be announcing my candidacy for the United States Senate. Arizona's Republicans deserve a choice and an alternative to Senator McCain¹s moderate record on taxes, social issues, the border, and bailing out the banks. I will be a consistent, faithful conservative that you can rely on to put Arizona first. This is going to be a great debate, and I need you. Please get involved by going to JD2010.com . (Disclaimer)
