Mostly because he's about as dense as lead, and politically as radioactive as plutonium to his buddies in the republican party, I guess that word has not gotten to the nether-regions of Rhode Island that the wing of the republican party currently in favor inside the beltway is not Sully-friendly. Imagine that. But like the little engine who could, Sully huffs and puffs about the Canadians recognition of all kinds of marriage.

Gay marriage is now a reality a few miles away from the United States.
...
Will the U.S. refuse to acknowledge a legally married Canadian couple? Will the U.S. refuse to acknowledge an American's marriage if she is married to a Canadian? There are all sorts of permutations to come.

Um, yes..what was the question again? Permutations? There are some of his fellow republicans who would like to make that word illegal in this country, much less anything it describes...

Remember, Andrew, It's all about 9-11 here in America..for us or against us!! and our neighbors to the north think Smirk is a moron, and we're all warmongers. Hence many republican 10-watt luminaries seem to feel we should not even be talking to the Canadians (damn furriners) anyhow, and you're wondering how these 10-watt lawmakers are going to treat a gay couple married in the great white north? Can I buy some of what you have been smoking?

Oops...my bad on the geography here, having been a New Englander but not a resident of the Great State of Massachusetts, I moved the entire city of Provincetown to Rhode Island with the click of mouse. My apologies to both cities and states...I'm sure that Rhode Island would be no happier to have Sully than Massachusetts is.
