Marco Rubio donors spent $25M in Florida primary loss to Trump

Wealthy donors handed over $25 million US last month to an outside group backing thenRepublican presidential candidate Marco Rubio, and the flood of money helped pay for thousands of television advertisements.

Rubio-aligned Conservative Solutions PAC aired more than 2,300 commercials since Super Tuesday on March1, according to Kantar Media's campaign analysis group. The political action committee was expected to shell out $9.6million US on radio and TV by March15.

It still wasn't enough.
