Montana Republican Senate candidate Matt Rosendale has raised over $700,000 in the three weeks following his June 5 Republican primary victory.

Tester's campaign has not yet released his latest fundraising numbers. In mid-May, Tester had more than $6 million in the bank.

Both candidates also have been aided by groups outside of Montana who have spent millions of dollars to support their campaigns.
