BIRMINGHAM, Ala. - As he explained his presidential goals, Mitt Romney said  his promises carried more weight than a typical politician's because he was  grounded in business, not politics. But he was quick to admit that his time as governor of Massachusetts and his  pursuit of the presidential office did,  in a way,  put him in the politician category.

"If I'm president, we're going to cut federal spending, we're going to cap federal spending, and we're finally gonna have a balanced budget. And by the way, politicians always say that. But I'm not really a politician. I guess I kinda am, because I was governor for four years and I've run for office.  But my heart is [that of] a conservative businessman," said Romney before a crowd at Thompson Tractor.

As he rounded out his swing through the South before Tuesday's primaries in Alabama and Mississippi, Romney used a set of charts to outline his plans for unions in this country and made the case for increasing investment in military forces.

"A strong military, military superiority, unquestioned military superiority is the best defense against terror and against war in the world," said Romney.

Romney contrasted his military plan to that of President Obama, arguing that the president supports decreasing military spending and personnel while increasing the costs of the military's health care program, posing a risk to veterans, their families, and troops currently serving abroad.

"Our troops, you know have been stretched to their breaking point by multiple rotations going into Afghanistan and formerly into Iraq, and yet this president wants to slow down purchases of ships, slow down purchases of new aircraft, reduce our military active duty personnel by 50,000 to 100,000, and now he is also proposing increasing the cost to our veterans and military families with Tricare,  the military health care program," said Romney. "My plan is entirely different than that. I want to increase our number of ship purchases per year by 9 to 15. I want to add more aircraft to our fleet. I want to have 100,000 additional active personnel, and I want to give our veterans the care they deserve."

After he labeled  it  an "infomercial" earlier this morning, Romney repeated his attack on the upcoming release of the Obama campaign's 17-minute documentary about the president's first term in office, and highlighted the need for the producers to note the "problems" of the administration, not just the successes.

"I'll remind Mr. Guggenheim about the problems," said Romney. "This president has made more than a few mistakes. He's made almost all mistakes."
