Bruce, aside from the obvious bias in the "issue" selection and questions, it's no surprise that most respondents favored the Republicans, with the way that the "mainstream media" (not to mention 90& of political talk radio shows) present the "issues" and news about them.
Let's not forget that an alarmingly high percentage of Americans still believe that Saddam Hussein was behind the attacks on 9-11-01, that Obama is a Muslim, that Obama raised taxes on the middle and lower income tax brackets, that Obama was not born in the US, that Social Security is bankrupt, that Al Gore claimed to have invented the internet, that a heavy snowfall in NYC in winter is inconsistent with global warming, that you can be a communist and a fascist at the same time, and many other erroneous ideas.

The TV news and commentary shows - even the ones that people don't think of as biased - present "information" and issues and ideas in simplistic form at best. They often allow political spokespeople to spout their party's talking points without question. When they do present a controversy, it's usually in a form like "Environmentalists say ____, while others say _____." They seldom play referee, clarifying issues and correcting misperceptions, even when the facts are easy to find and pretty much undisputed.

There are other good, scientific polls where people are asked their views on specific issues (clearly worded and more specific, not just vague terms), and on those the majority of Americans agree more with the views of Democrats and liberals/progressives than with the conservatives or Republicans.
