Senators are digging in for a long fight over President Obama's Supreme Court nominee.  

Lawmakers in both parties spent hours on the Senate floor Wednesday blasting the other party's rhetoric as Republicans remained united behind blocking Obama's eventual nominee. 
Democrats boiled down their argument to three words, repeatedly telling Republicans to "do your job" by agreeing to take up President Obama's pick to succeed Supreme Court Justice Antonin Scalia.

"If the majority leader sincerely believes that the only way to ensure the voice of the American people is heard is to lop off a last year of an elected official's term, I trust he will make these changes [to Congress]," he said. 
But Republicans hit back that Democrats are trying to cut voters out of the process by pushing through a third Supreme Court nominee for Obama during his final year.

Reid took a direct shot at Grassley Wednesday, asking if the Iowa Republican wants to remembered as the "least productive" and "most obstructive Judiciary chairman in history."
