When Barack Obama announced last week that he would opt-out of public financing for the general election, it became an instant campaign issue. Because Obama promised to take public funds, and agree to limit fundraising, earlier in the campaign, the decision left a huge opening for John McCain's campaign to seize on the issue.

Will this be an issue for you come November?
