Republican hopes for attracting more Hispanic voters suffered another setback on Friday when the House passed a bill to effectively end President Obama’s program to defer deportations of undocumented children. Yet the vote is unlikely to deal a severe blow to the party’s chances in November’s midterm elections. Hispanic voters may be flexing their growing political muscles in presidential elections, but they have far less sway over the composition of the House or the Senate, particularly in 2014.

Hispanic voters are all but absent from this year’s most competitive Senate battlegrounds. Hispanic voters make up about 11 percent of eligible voters but represent 5 percent or fewer of the eligible voters in eight of the nine states deemed competitive by Leo, The Upshot’s Senate model. Hispanic voters tend to turn out at lower rates in off-year elections than non-Hispanic voters, so it is likely that Hispanics will represent an even smaller share of the electorate than their share of the eligible voting population.

The only state where Hispanic voters could make a big difference this November is Colorado, where Hispanics represent 15 percent of eligible voters. But even there, it is important not to overstate the significance of Friday’s vote.
