This is a good site (I'm sure many of you have seen it) that can help sort out where people stand on what. It takes 20-25 topics, both social and political, such as tax reform, gun control, health reform, energy, education, abortion, budget, etc, and gives quotes (and links to the interview or speech from which the quote was taken), shows voting records, etc.
In the end, it takes all of these things (quotes, votes, etc) and summarizes where a politician stands
overall.
They show it on a graph that looks like this...
Fred Thompson's chart
Nancy Pelosi's chart
There is also a section where you can go through and answer certain questions and it will show where you stand on the chart.
