We move up the Latino and every other vote by actually expressing a message of independence and opportunity. Most Latin Americans came here because they thought they’d have a shot at developing a business and a life, and many of them have. That’s true of any group that was not brought here on welfare.
Africans (such as the Somalis or even Obama’s auntie Zeitunga) are usually brought here on some kind of welfare program, and these programs need to stop right now, although Obama has expanded them enormously at the cost of the Latin American quota.
So get rid of the special welfare immigration programs (which benefit mostly people from Muslim countries) and just start preaching economic opportunity and personal freedom to everybody, not just Latinos.
Also, stop thinking that anybody with a Spanish last name is a wetback. Many people with Spanish last names in the Southwest and California have been here for centuries, long before the Anglos arrived in their areas. These places were traded back and forth between Spain, Mexico and the US for many years as the geopolitical situation of these countries changed.
So another big thing the GOP could do is actually stop focusing on Latinos on a last name basis and just think that a Lopez could be as long-term (or more) an American as a Smith.
Maybe many of them don’t want independence and opportunity. Maybe we’ve already got the ones who want that (about 30%), and the rest of them like dependence on the gov. just fine. And according to analysts like Heather MacDonald, most Latinos are to the left of your average non-Latino Dem on social issues. Which means they like abortion-on-demand and other very lib. social policies.
