On Saturday, Hillary Clinton endorsed Barack Obama – too little, too late?

Some called Sen. Clinton’s speech Saturday, in which she suspended her bid for the Democratic presidential nomination and endorsed Sen. Obama, one of the best of her life. Critics said it was too little, too late, and that she snubbed Sen. Obama when he wrapped up the nomination early last week. Is she angling for the vice president spot? Is she secretly hoping Sen. Obama will lose? Or is she ready to campaign vigorously for Sen. Obama? Will it help Sen. Obama beat Sen. John McCain in November?

Gas is $4 per gallon – time to sell the Hummer?

Consumer surveys have shown that $4 per gallon gasoline represents a tipping point for most people. It’s the price at which most Americans will begin to change their driving habits. Will you alter your driving now? Are you able to do so? What steps will you take? How much of your driving is discretionary, and how much is necessary?

Are genetically engineered crops killing the bees?

Reader takei asks: In light of the news article “Nation’s beekeepers trying to rebuild” (BDN, May 31-June 1), which describes the unexplained “colony collapse disorder” destroying honeybee colonies, is it possible that pollen from genetically engineered crops are the reason bee colonies are dying? What else do we not know about GE crops?

Time for a revolution?

Reader Richard ponders: There is a line in the Declaration of Independence that states it is the responsibility of the people to overthrow the government when it has become corrupted by greed or fails to abide by the people’s wishes and needs. Have we reached that threshold? Our state government is spending out of control and the federal government is just plain out of control. Is it time for another revolution?

The Celtics in… four?

Las Vegas odds makers had the Los Angeles Lakers as 2-1 favorites over the Boston Celtics in the NBA championship series. Now that the Cs have won the first two games, some of those Vegas types may be sweating more than Kevin Garnett after a fast break. Will the Celtics take two from the Lakers in L.A.? Or will they win just one out West, and win the championship on the parquet of Boston? Or is Kobe Bryant just getting warmed up?
