Battle of the TV ads in US primary elections
Opponents have criticised the money spent by Mitt Romney on the Republican primary elections in Florida, where he had a resounding victory.
He polled 46% of the vote, with his closest rival Newt Gingrich on 32%. Mr Romney spent more than US$15m in the last month alone, funding 13,000 television advertisements.
Mark Mardell reports from Florida.
