TV scene of €1bn battle of negative advertising

The race for the White House has seen viewers deluged by over a million TV ads, with little evidence that voters have been swayed, reports Jeanne Cummings

BETWEEN Sept 11 and Sept 17, after the two political conventions and as undecided voters began to tune in to the presidential campaign in earnest, President Barack Obama, Mitt Romney, and the outside groups that support them spent $20m on television advertisements across 10 battleground states.

Last week, their last chance to influence voters, the two sides spent $30m — in Ohio alone.
