Obama: Achieved landmark overhaul putting U.S. on path to universal coverage now that Supreme Court has upheld the law's mandate for almost everyone to obtain insurance. Under the law, insurers will be banned from denying coverage to people with pre-existing illness, tax credits will subsidize premiums, people without work-based insurance will have access to new markets, small business gets help for offering insurance and Medicaid will expand.
Romney: Promises to work for repeal of the law modeled largely after his universal health care achievement in Massachusetts because he says states, not Washington, should drive policy on the uninsured. Says he would protect people with pre-existing conditions, though his plan only does so for those who maintain continuous coverage, not a major change from federal protections in effect before Obama's health care overhaul. Would expand individual tax-advantaged medical savings accounts and let savings be used for insurance premiums as well as personal medical costs.
Obama: Issued directive in June that immigrants brought illegally to the United States as children be exempted from deportation and granted work permits if they apply. Took the temporary step after failing to deliver on promised immigration overhaul, with the defeat of legislation that would have created a path to citizenship for young illegal immigrants enrolled in college or enlisted in the armed forces. Says he is still committed to it. Government has deported a record number of illegal immigrants under Obama.
Romney: Favors U.S.-Mexico border fence, opposes education benefits to illegal immigrants. Opposes offering legal status to illegal immigrants who attend college, but would do so for those who serve in the armed forces. Would establish a national immigration-status verification system for employers and punish them if they hire noncitizens who do not prove their authorized status. Would end visa caps for spouses and minor children of legal immigrants. Would honor work permits for immigrants who benefit from Obama's new policy but not accept new applicants under the program, and promises to put in place a comprehensive immigration plan before those permits expire.
Obama: His health care law improves coverage for beneficiaries with high prescription costs and removes co-pays for a set of preventive benefits. It also cuts Medicare spending for hospitals and other providers by more than $700 billion over a decade. Those cuts are being used to provide health insurance to more working-age Americans, and the government also counts them as extending the life of the program's giant trust fund. But he hasn't ruled out increasing costs for middle-class and upper-income Medicare recipients or increasing the eligibility age from 65 to 67.
Romney: Introduce "generous" but undetermined subsidies to help future retirees buy private insurance or join a government plan modeled on traditional Medicare. Gradually increase eligibility age to 67. Repealing Obama's health care law would roll back improved benefits for seniors unless Congress acts to protect them. It also would reverse Obama's Medicare cuts to hospitals and other providers, which could hasten insolvency of Medicare's trust fund.
Obama: Has not proposed a comprehensive plan to address Social Security's long-term financial problems. In 2011, proposed a new measure of inflation that would reduce annual increases in Social Security benefits. The proposal would reduce the long-term financing shortfall by about 25 percent, according to the Social Security actuaries.
Romney: Protect the status quo for people 55 and over, but raise the retirement age for full benefits for the next generation of retirees by one or two years and reduce inflation increases in benefits for wealthier recipients.
Obama: Wants to raise taxes on the wealthy and ensure they pay 30 percent of their income at minimum. Supports extending Bush-era tax cuts for everyone making under $200,000, or $250,000 for couples. But in 2010, agreed to a two-year extension of the lower rates for all. Wants to let the top two tax rates go back up 3 to 4 percentage points to 39.6 percent and 36 percent, and raise rates on capital gains and dividends for the wealthy. Health care law provides for tax on highest-value health insurance plans. Together with Congress, built a first-term record of significant tax cuts, some temporary.
Romney: Keep Bush-era tax cuts for all incomes and drop all tax rates further, by 20 percent, bringing the top rate, for example, down to 28 percent from 35 percent and the lowest rate to 8 percent instead of 10 percent. Curtail deductions, credits and exemptions for the wealthiest. End Alternative Minimum Tax for individuals, eliminate capital gains tax for families making below $200,000 and cut corporate tax to 25 percent from 35 percent. Does not specify which tax breaks or programs he would curtail to help cover costs.
Obama: Approved the raid that found and killed Osama bin Laden, set policy that U.S. would no longer use harsh interrogation techniques, a practice that had essentially ended late in George W. Bush's presidency. Largely carried forward Bush's key anti-terrorism policies, including detention of suspects at Guantanamo Bay despite promise to close the prison. Expanded use of unmanned drone strikes against terrorist targets in Pakistan and Yemen. The deadly attack by militants on the U.S. Consulate in Benghazi, Libya, in September raised questions that persist about the quality of U.S. intelligence and about why requests for added security there were denied before the assault.
Romney: No constitutional rights for foreign terrorism suspects. In 2007, refused to rule out use of waterboarding to interrogate terrorist suspects. In 2011, his campaign said he does not consider waterboarding to be torture.
Obama: Ended the Iraq war, increased U.S. troop presence in Afghanistan then began drawing down the force with a plan to have all out by the end of 2014. Approved U.S. air power in NATO-led campaign that helped Libyan opposition topple government. Major cuts coming in the size of the Army and Marine Corps as part of agreement with congressional Republicans to cut military spending over a decade.
Romney: Proposes increase in military spending. Endorses 2014 end to U.S. combat in Afghanistan. Would increase strength of armed forces, including number of troops and warships, adding almost $100 billion to the Pentagon budget in 2016. In addition, criticized congressional Republicans for negotiating a deficit-cutting deal with the White House that will mean automatic and massive cuts in Pentagon spending next year if federal budget deal is not reached in time.
