Latino lawmakers and organizations are furious over the Senate’s failure to break a GOP filibuster of the nomination of recess appointee Mari Carmen Aponte to remain in her post as ambassador to El Salvador.

The Obama administration and Senate Democrats fell 11 votes short of the 60 needed to bring the nomination to a vote. Without confirmation, Aponte will lose her ambassadorship at the end of this year.

Rep. Nydia Velazquez (R-N.Y.) said he “promised to be the voice of Puerto Ricans in the Senate” but declined to “use that voice in support of a Puerto Rican woman who has shown she is immensely qualified.”

Well, Florida’s 850,000 Puerto Ricans are seen as a critical and growing voting bloc, although they made up only about 4 percent of the vote in 2010, according to the Pew Hispanic Center’s analysis of census data. And Rubio’s not up for reelection until 2016.

Of course, Obama and all House members are up next year.
