Senate Vows To Block Obamas Supreme Court Justice Nominee v According to Republican Senate Majority Leader Mitch McConnell, the U.S. Senate should not act to fill the Supreme Court vacancy opened by the death of Justice Antonin Scalia until after President Obama is out of office. The American people should have a voice in the selection of the next Supreme Court justice, McConnell said in a statement. Therefore, this vacancy should not be filled until we have a new president. Several other Republican leaders, including candidates Sen. Marco Rubio and Ted Cruz, have also come forward with their opposition to President Obama choosing the Supreme Court nominee. The Republican majority in the Senate is helping to build a strong case against Obama, but any action taken would include some serious risks. In any case, Obama will be under pressure to choose a more moderate justice in order to win the Republican votes he needs. If Republicans are unable to retake the White House in 2016, the pressure evaporates. And experts fear that it will be less likely the case if Donald J. Trump or Ted Cruz get the GOP nomination. What do you think? Do you support a block against President Obamas nominee?
