Republican presidential candidate Mitt Romney is campaigning in conservative-leaning northwest Iowa today, telling crowds this is an election about tomorrow not yesterday.

Romney warned that Islamic extremists, such as those blamed for the assassination of Pakistani politician Benazir Bhutto, present a unique challenge for the U.S.  "A very different kind of foe than we’ve faced before and we’re going to have to respond in new ways with a comprehensive effort to help Muslims reject the extreme and to support the voices of moderation and modernity in the world of Islam," Romney said in Le Mars.

Romney has been touting his work as governor of Massachusetts to devise a system which has seen nearly 300,000 previously-uninsured Massachusetts residents acquire private health insurance. "We need to make sure that every American has health insurance that is affordable but that is not associated with a government take-over because we don’t want Hillary-care or socialized medicine," Romney said in Le Mars.

According to Romney, other people running for president have health care "ideas" — an apparent jab at rival Rudy Giuliani who has outlined a set of principles which Giuliani vows to follow when setting health care policy and at competitor Mike Huckabee who has stressed the need to refocus the health care system on preventing rather than curing disease. Romney, though, presents himself as the only candidate for president who can point to a "success" in health care reform.
