In the 2012 presidential election, seven out of 10 Latino immigrants voted for President Obama. News pundits declared the Latino vote as unattainable for the Republican Party.

Yet Latinos voted for President George W. Bush - and as governor too. While African-Americans are regarded as solidly one-sided, Latinos are courted by both parties because their votes are 'in play', they are not voting for one party despite what news media claims. They are socially conservative and religious, which are Republican strengths, yet want immigration reform, which Democrats champion.

Recent electoral trends in U.S. elections are in defiance of the center or center-right ideologies among Mexican immigrants, notes University of Nebraska-Lincoln political scientist Sergio Wals in Electoral Studies. But illegal immigration is a hot topic and they have sided with reform and amnesty rather than a hard line.

"If you look at survey data from Mexico, from 25 years ago -- which is systematic, good empirical evidence -- and you look at the distribution of ideological preferences, it remains fairly stable for the most part. But it has always been heavier on the center, center-right than on the left," Wals said. "I know there's been a historic trend where anywhere from 60 percent to the current 70-plus percent of the Hispanic vote has gone Democratic, but there are clear exceptions to these national trends."

Wals, an assistant professor of political science, said the parties in power in his home country of Mexico over the last 35 years have implemented right-leaning economic policies. It makes sense, then, that many immigrants come to the United States with more conservative views.

He points to other factors: "For the most part, you have a fairly conservative population (in Mexico) in moral terms, religious terms and even in the recent economic policy history."

Wals' findings are based on a national survey of 399 Mexican immigrants and a survey-embedded experiment of roughly 1,000 Mexican immigrants in Texas and Indiana.

The participants had been in the United States an average of 17 years. The study found that about 70 percent of Mexican immigrants considered themselves in the same ideological place as they were when they were still living in Mexico.

So what might the findings mean for the future of American politics?

"This is enough evidence for the two parties to take a little pause and take these findings seriously, for the Democratic Party not to take the Latino vote for granted and for Republicans not to think it's a lost cause," Wals said. "If Republicans were to work on outreach strategies and intelligent ways to incorporate this population into their platforms, I definitely think they would fare a lot better than they have in the past."

Both parties also need to make efforts to better understand the immigrant population.

"'Latinos' is this pan-ethnic label that has been superimposed on a number of groups, (but) there is a wide range of variation and even within national origin, there is a wide variation," Wals said.

Wals concludes that the political parties need to engage immigrants early on in the immigration process, since the population is "more up-for-grabs than generally depicted in electoral terms."

"It's not that it's a predetermined sort of thing," Wals said. "There is room for adjustment. Those ideologies are an anchor and there's room for adjustment for some of these folks."

Wals said he plans to help explain more about immigrant political ideologies with further research on how ideologies change and how political beliefs translate into choosing a political party, when there is no exact match. He theorizes that this may ultimately explain why center-left immigrants are less likely to be politically involved.

"Overall, you can see people from the leftist party, the Democratic Revolution Party in Mexico, probably having more chances to become Democrats in the U.S.," he said. "At the same time, it's not a direct translation to the point that people on the left from Mexico actually have much more trouble finding themselves being interested in politics in the U.S. because they might not have a good party match."
