Hispanic voters view the Democratic Party more favorably than the GOP -- but not by as wide a margin as they did in 2012.

That's one of the key findings in a new Pew Research Center poll released Wednesday. Trust in Democrats to look out for them has dropped among Latino voters, while it has held steady among Republicans.

The following charts tells the story. In 2012, 61 percent said the Democratic Party had more concern for them. Now, 50 percent do. The percentage saying there is no difference between the two parties has jumped from 23 percent to 35 percent. That's more in line with where the numbers were between 2002 and 2010. (Democratic support jumped up between 2010 and 2012)

The findings come toward the end of a Congress in which the Democratic-controlled Senate passed a sweeping immigration reform bill that included a path to citizenship for undocumented immigrants. The GOP-controlled House refused to take it up.

President Obama has vowed to take executive actions to remake immigration policy. The White House said in September that he would delay those actions until after the midterm elections.

Thirty percent of Latino voters say they did not hear about the delay. Among the ones who did, more were disappointed (26 percent) than pleased (19 percent) with the decision. The poll also shows that more Latino voters blame congressional Republicans for inaction on immigration than Obama or congressional Democrats.

Many Republican strategists have expressed worry that Republicans have hurt themselves since 2012 among Hispanic voters, who make up a growing share of the presidential electorate and have voted overwhelmingly Democratic the last two times. But as the Pew poll shows, Democrats should also be concerned about their standing among Latino voters.
