Schatz, who was appointed to the Senate in late 2012 following Sen. Daniel Inouye's (D-Hawaii) death, has brought in $3.4 million for the campaign, while Hanabusa has raised $1.6 million. Neither campaign has released its cash on hand figures.
Hanabusa was Inouye's choice to replace him — he made the request on his deathbed — but Hawaii Gov. Neil Abercrombie (D) instead appointed Schatz, his ally and then-lieutenant governor. Hanabusa decided to challenge Schatz shortly thereafter.
