PHOENIX - The Mitt Romney campaign said today that it raised nearly $12.6 million in primary funds in March, bringing the total of primary contributions over the past 12 months to $87 million.

According to the Romney campaign, it has no debt and $10.3 million in cash on hand, an uptick from the $7.3 million it had at the end of February.  Romney has given no money from his own personal fortune to his campaign.

"Mitt Romney's continued strong fundraising shows that voters across the country are tired of the failures from President Obama," said Romney's National Finance Chair Spencer Zwick in a statement. "We will continue the hard work to raise the necessary funds to defeat President Obama and change the direction of the country."

Small donations continued to rise for the Romney campaign, with 64 percent of all donations coming in for amounts of $250 or less - that's 286,520 donations.

While the Romney campaign focused entirely on primary funds in March - when the candidate's chief GOP rival Sen. Rick Santorum was still in the race - the focus has since shifted to general election fundraising. The Romney campaign has a joint fundraising account with the Republican National Committee that has already held several high-dollar fundraisers across the country, with another one slated for this evening in Arizona.
