5. Obama's Supreme Court pick ignites partisan acrimony. 

President Barack Obama on Wednesday announced his intent to nominate federal Judge Merrick Garland to fill the the late Antonin Scalia's seat on the Supreme Court, formally kicking off a bitter election-year battle with Senate Republicans that could overshadow all other work in Washington in the lead-up to the November races.
