Memo to Hillary Clinton: Close counts only in horseshoes and darts.

Sometime in the next week or so, if not sooner, Democratic presidential candidate Barack Obama will have clinched his party’s nomination. Why won’t Sen. Hillary Clinton, who will finish a very close second in the race for the nomination, drop out? What is your theory on why she persists in keeping her presidential bid alive? Is she justified, or selfish? Will Sen. Obama offer her a role in his administration (if he wins in November)? Should he?

What will be the next business threatened by high oil prices?

Last week, Katahdin Paper Co. in Millinocket announced that it plans to close its facility because of the high price of oil. The mill uses millions of gallons of oil each year to operate its machines. Is this the beginning of a new exodus by businesses to warmer climates? What can be done to help such businesses? What about homeowners? Many will struggle to pay heating oil bills this winter and they can’t close down. Are alternative energy sources feasible? What can jump-start the switch?

Sex, cities and Maine – which doesn’t belong and why?

Why would a movie, based on an HBO TV series, set in New York City and centered on the lives of four chic and well-heeled (in both senses of the phrase) women be popular in Maine? Is it because we secretly yearn for a lifestyle of cocktails, lunch at trendy restaurants and R-rated gossip? Bonus question: If there were a Maine version of this show, what would it be called? “Shivering by the Wood Stove in the County”?
