Worthless polls

Here's a great example, from today's Baltimore Sun:

Do you approve of Gov. Martin O'Malley's plan to balance the budget through a combination of program cuts, fund transfers and an expected infusion of federal funds?

Yes / No / Not sure

But you could be against it because you don't think Maryland can afford to cut services and should raise taxes instead, or don't expect federal funds, or don't think a balanced budget is a desirable goal, or for some less easily described reason - or just because you hate O'Malley. What's the point of a question like that? 75% of respondents say "No" won't give you any useful information.

At least it's not pretending to be scientific...
