That was the total pledged to Marco Rubio’s U.S. Senate Republican primary campaign against Gov. Charlie Crist in a pair of online fund-raisers known as “money bombs.”

It’s a huge number.

It doesn’t beat Crist’s best stretch of this race (he collected $1 million over three days in June). But it is 25 percent of what Rubio raised in the first nine months of his campaign and 41 percent of all the cash he had on hand to start the year, about $2.1 million.

Crist reported a total of $7.6 million in campaign cash to start 2010.

The money bombs also brought more than 8,000 donations directly to the campaign. As a comparison, Rubio’s campaign had about 11,000 donors through its first six months.
