Restore Our Future, the super PAC backing Mitt Romney, saw its fundraising fall by almost half the previous month’s haul. In April, the group brought in $4.6 million; in March, ROF raised $8.6 million. Still, the group ended the month with $8.2 million cash on hand, more than the $6.5 million they had on April 1. The group spent over $2.8 million in April.
