Washington (CNN) -- No more robocalls interrupting dinner or angry campaign ads at every TV break -- the most expensive mid-term elections in history finally take place Tuesday, when voters decide who goes to Congress and governors' offices.
Polls indicate a dissatisfied electorate may clean house -- literally -- by tossing out the Democratic majority in the House of Representatives and possibly doing the same in the Senate.
With all predictions, including those of Democrats, signaling Republican gains, the election is considered a referendum on both the Democratic-controlled Congress and President Barack Obama's first two years in office.
