The Democrats have promised a green convention and now, environmental concerns threaten to deflate an old-time tradition at nearly every convention---the last night balloon drop.
Thousands of balloons typically drop on a convention's last night after the candidate formally accepts his party's nomination. But, with the Democrats moving their convention to the outdoor Invesco Field at Mile High Stadium for their final night, concerns that the balloons could harm the environment could mean a decision not to let any loose this year, according to news reports.
Republicans say they have concerns, too, but with their convention being held indoor at Xcel Energy Center, balloons are still scheduled to drop as planned.
