As of June 30, the date of the most recent campaign finance reports, Romney edges out Obama in terms of money raised, $43,750 versus $42,675, the Center’s analysis indicates.

Both men have favored health care policies that include an individual mandate for people to purchase private insurance plans. Romney did so as governor of Massachusetts, and Obama did so as part of the health care reform package he signed into law last year — a package that did not include a public insurance option to compete against private plans, as many liberals hoped it would.

Such mandates are supported by the insurance industry, which stand to benefit from increased customers as well as from government subsidies that help enroll people who could not otherwise afford insurance.
