With less than a month remaining before the 2014 midterm elections, advocates say Latino voters may hold sway over the congressional and senate races but turnout rates remain unclear.

Advocacy group Latino Decisions estimate Latino votes could influence the outcome in 14 Republican- and 10 Democratic-held districts, and five Senate races in key states this November.

However, the administration's failure to pass an immigration resolution and President Barack Obama's postponement on executive action on the issue may discourage Latino's enthusiasm to participate in the 2014 elections.

National voter registrations carried out in January by the Mi Familia Vota and National Council of La Raza (NCLR) hoped to get 250,000 Latino registrations in at least six states. As of Monday, 80,000 registrants were recorded with an additional 10,000 more expected, falling short of the groups' projections, said NCLR CEO Janet Murguia.

Advocacy groups want people to vote, but if you're a Latino from North Carolina, and Obama delayed immigration action to help Kay Hagan's election chances, why would you vote for her, said Latino Decisions co-founder Gary Segura.

Even so, low Latino turnout for the November elections may also influence the results.

In the same way that voting for people can help them win, non-participation in the midterms could still make a difference, Segura added.

"The decision not to vote is still a political decision," he said.

Advocacy groups remain hopeful Latino voters would help determine the outcome of next month's elections, but cautioned against "headwinds" that could have an effect on turnout.

While the 80,000 Latino registrations fall short of this year's projections, the figure has already exceeded the mark for registrations in the 2012 presidential elections, said NCLR Deputy Vice President Clarissa Martinez de Castro.

Since the 2010 midterm elections, eligible Latino voters have increased 17.9 percent, which makes it more likely more Latino voters will turn out this year, said Pew Hispanic Center Hispanic research director Mark Hugo Lopez.

But Lopez noted that even with more eligible Latino voters, turnout may still remain low due to a number of reasons.

In the 2012 presidential race, Latino turnout was at a record high. Even so, a substantial number of eligible Latinos opted not to go to the polls.

Aside from immigration issues, Martinez de Castro notes concerns that could affect Latino turnout this November include voter ID regulations, voter registration campaigns, voter registration sources from independent parties and lack of involvement from both sides.
