2. The Latino vote
Obama received 67 percent of the Latino vote in 2008, and five key swing states (Arizona, Colorado, Florida, Nevada, and New Mexico) have a strong chance of increasing their Latino voter registration. Roughly seven percent of the voting public was Latino in 2010, and more are expected to turn out in a presidential election. The Republican candidate may have to push for a lenient stance on immigration to win stronger Latino support, but that may come at the expense of non-Latino Republican voters who want stronger enforcement of the borders.

About six immigrant rights activists were arrested Wednesday after entering a federal building and refusing to leave, the Los Angeles Times reported.

The San Gabriel Valley and Inland Empire Dream Teams, which consist of undocumented students and their supporters, organized the protests, according to the L.A. Times.

5 undocumented Students stage a sit in inside ICE headquarters in downtown LA federal building risking being detained by ICE, the San Gabriel Valley Dream Team wrote on its Facebook page.

Approximately 200 demonstrators were asking for an end to the Department of Homeland Security's Secure Communities program, the LA Times reported.

Under the Secure Communities program, the FBI sends fingerprints of people who are put in FBI jails to Immigration and Customs Enforcement to check against immigration databases.

If the checks show that someone is in the country illegally or otherwise removable due to a criminal conviction, according to the ICE Web site, the agency takes enforcement action.

According to Homeland Security spokesman Matt Chandler, the six arrests were carried out by the Federal Protective Service, Fox News Latino reported.
