Jonathan Paton's campaign has launched a round of automated phone calls with a new nickname for his democratic opponent: Kickback Kirkpatrick. The first call highlights Ann Kirkpatrick's spending during her last days in Congress.

The Paton Camp's press release cites a June 2011 Arizona Republic article that reveals Kirkpatrick spent more than $100,000 during their final days in office. Only three other departing House members paid out more money, according to the article.

The phone call echoes the sentiments of a National Republican Congressional Committee funded ad released Sept. 23 that alleges Kirkpatrick "snuck campaign aides onto payroll." See that and a House Majority PAC ad knocking Paton here.

District 1 Breakdown

As of the August 28 primary, there are just more than 361,000 voters registered in Congressional District 1. Democrats hold a slight advantage with about 38 percent over the Republican's nearly 31 percent, according to the Arizona Secretary of State.

The National Journal listed CD 1 as number 12 on a list of competitive congressional districts likely to switch colors on the map, at the end of August.

The new-ish CD 1 stretches from the Utah border to the northern edge of Cochise County. Eleven counties including Coconino, Pima, and Pinal County all have a toe (or more) in the CD 1 lake. Pinal County boasts more than 84,000 registered voters, the highest in the district.

In terms of total population, the district has a largest percentage of Native Americans in the state, with 162,087. The next closest is CD 3 which counts 22,441 Native Americans among its population.

Non-hispanic whites account for 50% of the district and Hispanics for about 20 percent. Find the full breakdown here.
