PHOENIX — Maricopa County Sheriff Joe Arpaio has raised nearly $2.5 million in campaign contributions over the last year.
Since winning re-election in 2012, the six-term sheriff has raised $7.9 million in contributions and has already spent $4.7 million of that amount.
He is now left with $3.2 million in cash on hand.
Many of Arpaio's contributors live outside of Arizona and made donations under $100.
Arpaio and six other candidates have filed paperwork saying they'll run in this year's sheriff's race.
The challengers include former Buckeye Police Chief Dan Saban, who ran unsuccessfully against Arpaio in 2004 and 2008.
Arpaio's campaign fund was depleted after his 2012 campaign, his second-closest race in his tenure as sheriff.
He spent $8 million during his 2012 campaign.
