Campaign finance reports filed Tuesday show Attorney General Tom Corbett has nearly $4 million on hand more than GOP gubernatorial rival state Rep. Sam Rohrer, giving the Republican front-runner a huge financial advantage in the campaign’s final six weeks.

Corbett has slightly more than $4 on hand after raising $1.77 million in the year’s first three months, finance reports provided by his campaign show. Rohrer, according to campaign senior strategist Jeff Coleman, has about $7,000 on hand after raising $172,000 this year.
