I'll go you one better, Shermclay.

You can use YouTube to "roadtest" speeches.  Review the feedback you get, try to get specific points raised by people who comment (and most specifically to ensure you know where they are coming from, etc...).

When you're done, you can show how your campaign has evolved by listening to the people of your district, state, whatever.

More comments than from a focus group, and more of a way to show where you are versus where you were.  If your message is wildly inconsistent, then you have something to answer for.  If it evolves over time or stays consistent, people can see you for what you consider important and judge accordingly, but they'll do so knowing with greater confidence who you really are.

Do it right, and you can be shown as someone calibrating their message.  Do it wrong, and you'll be justly accused of flip-flopping.
