Democratic state Sen. Barbara Buono has stepped up fundraising in her run for governor but still lags far behind incumbent Chris Christie when it comes to getting donations and spending them.

The state Election Law Enforcement Commission says that through June 24, Buono had brought in $3 million and Christie just under $7 million.

Both campaigns spent nearly all they brought in.

Buono's coffers include money from a state matching program that gives her $2 for every $1 she raises privately.

The Republican Christie is forgoing the program and the campaign spending limits that come with it.

The report also finds that incumbent legislative candidates are raising more than $12 for every $1 their challengers bring in.
