DENVER (AP) — Democratic Sen. Michael Bennet raised more than $1.6 million for his re-election campaign last quarter. His campaign announced the total Wednesday.

The senator is seeking a second term. His campaign says that Bennet has $5.4 million cash on hand.

Bennet has three Republican challengers, none of which had released their third-quarter fundraising totals Wednesday. One of those, state Sen. Tim Neville of Littleton, did not join the race until October, after the fundraising quarter had ended.
