Issues matter more than personalities.
Healthcare, while not specifically a 'gay' issue, since it effects everybody, is more important to gays because of the current health crisis.
While no health insurance system is perfect, the best solution to the health crisis from a gay perspective is not-for-profit national health insurance, like the Canadian system, since:
1) it covers everybody,
2) it gets superior results, based on published statistics such as life expectancy and infant mortality rates, and
3) it costs less, since its administrative costs are much lower.
The Canadian system's administrative costs are 3% of their health care dollar, while in the U.S. it is 18%. Why is the U.S. administrative cost so high? Because there are thousands of different health insurance plans, from hundreds of different health insurance companies. Each company has its own overhead, its own regulations, its own sales force, its own advertising, its own lobbyists, and, of course, its own need to show a profit. Private insurance profits increase when people are denied coverage and when people with very high medical costs are dropped from private plans.
The U.S. has had some government funded health care since 1792 (when George Washington was president) when the U.S. Public Health Service was founded to cover merchant seamen. Over the years, government coverage has expanded to include veterans, the elderly (Medicare), and the extremely poor (Medicaid.) Most AIDS patients wind up on Medicaid, but only after the government required impoverishment reduces their assets to below $200.
Kucinich supports a true not-for-profit national health insurance program like the Canadian system. Edwards, Clinton and Obama would all keep the current broken health care system, and encourage or mandate Americans to buy health insurance.
Support for Kucinich keeps the option of a true national health insurance system in the debate. And if enough people start supporting true not-for-profit national health insurance, then watch Clinton, Edwards and Obama support it. Conversely, if Kucinich drops out, watch the Clinton, Edwards and Obama positions move to the right and become more like the Republican position on health care, which is to maximize the profits of doctors, hospitals, and drug companies.
