Washington (CNN) -- After years of planning and months of campaigning, the most expensive presidential race in history comes down to a final five-day whirlwind of speeches and television ads in the eight states still up for grabs. President Barack Obama and Republican challenger Mitt Romney plan to hold virtually nonstop events between now and the Tuesday election considered too close to call. The focus is on battleground states worth 95 of the 270 electoral votes needed to win. Both sides are trying to close the deal with a dwindling number of uncommitted voters, while making sure supporters actually cast ballots.
