Border roundup: Suspect pleads guilty to murder in Brian Terry killing

Elections

An official Maricopa County letter may be the solution for voters on a state "suspense" list because of Arizona's two-track registration system which lets new voters register without ID using a federal form but leaves them without a voter registration card to show at the polls. This system especially affects out-of-state students who live in university dorms and don't have a property-tax statement, a state-issued driver’s license or a utility bill.

Voters may also be inactivated or receive letters asking them to prove their citizenship as politicians work to clean up voter rolls, especially in battleground states.

A Los Angeles Times poll on how California voters see immigration shows that as a group they are still " tough on border security and enforcement" but have changed towards people who are in the state illegally and "overwhelmingly" support the new federal program granting work permits to qualifying applicants who were brought to the United States as children as well as driver's licenses for the same group.

Senate candidates Richard Carmona and Jeff Flake challenged each other on immigration during their final debate, both accusing each other of abandoning for comprehensive immigration reform.

Economy

After a drop that started in 2008, illegal immigration is rising again, an indication that the United States economy is recovering, according to a report by the Tomas Rivera Policy Institute at the University of Southern California. Immigration reform may actually be key to the country's economic growth according to Bloomberg News, with high-tech industries having "the most to gain." The number of young illegal immigrants applying for the new federal program granting work permits to qualifying applicants who were brought to the United States as children is about 3,000 - daily.
