There are 303,600 legal immigrant in Arizona, enough to swing a few elections. But Latino immigrants historically participate in elections less than other immigrant groups. Advocates are hoping to change that:

By flooding polls, advocates aim to push the immigration debate away from the enforcement-heavy approach supported by many key lawmakers in favor of comprehensive immigration reform that offers a path to citizenship for undocumented immigrants and more visas to reunite families.

[Activist Ruben] Villarreal and others will concentrate on voter drives in Republican J.D. Hayworth's District 5, in parts of Mesa, Tempe and Phoenix, and Republican Jim Kolbe's District 8 in southern Arizona. Hayworth, a staunch immigration-control advocate, faces Democrat Harry Mitchell this fall, and a slew of candidates is battling for the seat Kolbe is giving up.

Not such good news for Rep. Hayworth, Randy Graf, or Don Goldwater.
