Gov. Neil Abercrombie raised $859,483 in the past six months for his re-election campaign, bringing his total to more than $3.3 million overall.
The Democrat had $2.1 million in cash on hand at the end of June, according to his latest campaign-finance report.
Abercrombie is being challenged by state Sen. David Ige in the primary.
“We are pleased with the overwhelming support and confidence in Governor Abercrombie's vision and the hard work of his administration,” William Kaneko, Abercrombie's campaign manager, said in a statement.
“Since taking office in 2011, Governor Abercrombie has had to make some hard decisions amid tough choices, which have led to positive results for our residents and businesses. We see visible signs of a strong economy, one of the lowest unemployment rates in the country, and a more responsive state government."
