The second time was the charm for Mari Carmen Aponte to become ambassador to El Salvador.
The Senate today voted 62-37 to end debate on the nomination, and within a hour of that vote, she had been confirmed by voice vote.
Sixty votes were needed to end debate on the nomination.
Todays vote was the second time the chamber considered the Aponte nomination. The Senate voted on the issue in December, but the nomination failed to win the 60 votes needed to beat back a filibuster.
Nine Republicans voted to move Apontes nomination forward, six of whom switched their votes from December to help Democrats overcome the filibuster. Democrats said the White House and the State Department spent the past few days calling Senators to urge support for Apontes confirmation.
With Democrats heavily courting the Latino vote ahead of the November elections, Apontes nomination was a priority for President Barack Obama and Senate Majority Leader Harry Reid (D-Nev.), who worked to keep it alive in the Senate.
Rubio voted against Aponte in the Foreign Relations Committee and on the floor in December. He said his opposition had to do with concessions he was seeking from the Obama administration regarding policy toward Latin America.
Once he won the concessions, he said he would vote for Aponte and help find the seven GOP votes needed to confirm her. He called on Reid to hold the vote later in December and said that he had secured the votes needed.
Democrats argue that Rubio only changed his position after getting heat from Puerto Rican constituents. Puerto Ricans are a key voting constituency in Florida, and Aponte is of Puerto Rican descent. Democrats also question whether the votes Rubio said he wrangled would have come through.
They also argue that Rubio opposed Aponte as a nod to Sen. Jim DeMint. The South Carolina Republican, who has embraced the tea party, endorsed Rubio early on over the GOP establishment candidate, then-Gov. Charlie Crist, which helped Rubio win.
DeMint had led opposition to Aponte, in part, because the administration refused to cooperate with Republican requests for information on her controversial background. He contends that questions remain about her relationship with a man who he said was targeted as part of an FBI counterintelligence investigation and allegedly worked for Cubas spy agency. He also opposed some of her writings that he said were pro-gay and anti-family.
Rubio said Wednesday that he believes Democratic leaders were playing politics with the nomination. He sought to place the blame on them if Aponte did not move forward.
