Massachusetts Sen. Scott Brown (R) raised nearly $2 million in the second quarter and had a whopping $9.6 million in cash on hand at the end of June, according to the Boston Globe.

Brown faces a tough re-election in strong Democratic territory, but his prospects should be buoyed by his substantial war chest. Democrats have made the Republican their primary target for 2012, and some people on the right have complained he is not conservative enough.

Brown won his Senate seat in the special election in January 2010 to fill the vacancy left by the death of Sen. Edward Kennedy (D).

Six Democrats are competing in the Bay State primary to take on Brown next year. One of them, City Year co-founder Alan Khazei, released his fundraising numbers Tuesday. He raised more than $920,000 in the quarter.
