(CNN) - Even before the current economic crisis, voters listed the economy as the top issue in the presidential election.
In a CNN.com special report, Battleground Voters, we talked to voters in five battleground states - Colorado, Florida, Missouri, North Carolina and Ohio - to find out how the economy would influence their choice for president.
In the third of four parts, we talked to retirees, who say they're not only worried about their own finances, and whether they may need to work again, but about others, and the kind of world that their children and grandchildren will live in.
CNN's special report on battleground voters continues Friday with a look at unemployed voters.
