Most United States residents really don’t know whose health care plan is better for them, Obama’s or McCain’s, a recently-conducted poll showed.

The poll was carried out in September by the Harvard Public Opinion Research Program at the Harvard School of Public Health and Harris Interactive. The survey included 935 voters and 4 in 10 of them said that they have no idea what presidential candidate has a better health care plan. In other words (numbers actually), 27% of the registered voters said they didn't think there was much difference between the two health care plans, while 13% just did not know if there'd be a difference.

Of the voters who did know or thought they know what presidential candidate had a better plan, 33 % favored Obama’s, while only 27% were for McCain.

However, considering the width, depth and complexity of the two health care programs, it’s hard to imagine that, of those who did pick one of the programs, many really knew what they were talking about.

It’s probably true. Most people didn’t study the programs themselves. But their interest in the matter existed and they picked information from secondary sources.

"The majority of people never look at the plans. [Instead] they cue off media coverage, people they respect. If they're partisan, they cue off party leaders. If they run a business, they cue off the chamber [of commerce]," said professor Robert Blendon at the Harvard School of Public Health.

So the poll might be relevant after all. For those of you interested in the two health care plans, here they are:

Obama’s Health Care Plan
