Washington, November 1, 2012  (CNN) -- After years of planning and months of campaigning（竞选）, 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 decreasing number of uncommitted(未表态的) voters, while making sure supporters actually cast ballots.

That means a game of campaign chess that started Thursday, with appearances by the candidates (候选人)and their assistants as well as advertising dollars allocated to the places considered most vital to success.

Concluding a race expected to cost more than $6 billion overall, Obama and Romney and their running mates will hit all the battleground states -- Colorado, Florida, Iowa, Ohio, New Hampshire, Nevada, Virginia and Wisconsin. The campaigns also are unloading a blast of television ads and mailings that threaten to overwhelm voters already saturated with politicking. Perhaps no one said it better than 4-year-old Abigael Evans of Fort Collins, Colorado, who -- according to NPR -- cried after listening to more election coverage on the radio and told her mother, ‘I'm tired of Barack Obama and Mitt Romney.’
