“Under Democrat rule, the Senate has become the place where serious legislation comes to die, a graveyard for good ideas,” McConnell said on the Senate floor.

McConnell said Senate Majority Leader Harry Reid (D-Nev.) is preventing the Senate from considering job-creating measures because the Nevada Democrat has blocked amendment votes on legislation.

McConnell said Senate Democrats are politically motivated because President Obama doesn’t want to be forced to veto GOP measures, as Republicans control the House.

“That’s a main reason why President Obama wants so badly to keep his Senate majority this November,” McConnell said. “It’s his castle moat, the last thing standing between him and having to sign serious legislation the middle class deserves but the far left hates.”

On Monday, Republicans blocked progress on a bipartisan energy efficiency bill because Reid wouldn’t allow at least five GOP amendment votes.

Republicans have also blocked Democrats’ attempts to bring up legislation that would increase the federal minimum wage and ensure equal pay for women. McConnell has called these “political show votes” designed to help Democrats get reelected in November.
