Most Americans think the Iraq war was a mistake. So what?

Vice President Dick Cheney, when told by a morning news TV show host that most Americans viewed the invasion of Iraq as a mistake, replied, “So?” He later said the opposition was not a surprise, and that decisions as serious as going to war should not be based on public opinion polls. Do you agree? Should decisions by government take into consideration public opinion? When it is it appropriate and when is it not?

Do you scratch? What would make you scratch more?

State lottery officials are hoping to boost annual revenues from $50 million to $60 million, and are using focus groups to learn how to lure more people to buy lottery chances. Scratch tickets are more popular than the Tri-State Megabucks, and research has found that the design of the scratch tickets affects their popularity. Online lottery use is also a growing sector. Which lottery form are you most likely to participate in, if any? Can – and should – the state Lottery Commission work to increase sales?

Should the Fourth of July be the first day of summer vacation for Maine students?

With all the snow days used by Maine schools this winter, many won’t close for summer vacation until June 20. Should the state waive the snow days and end school at the usual date? Or is it important that students get in a full school year? Extra credit question: Should the U.S. go to a year-round school calendar?
