The article you linked confirsm what I said and flatly contradicts your claim:
And state Department of Revenue spokesguy Bob Bliss confirmed the senator is under no obligation to pay the commonwealth sales tax.
Did you read the article yourself?
I would very much appreciate any source that would confirm your claim, which I believe to be at odds with the facts, that Kerry violated the law.
That is untrue and coming from a fellow Democrat. The rest of the article was true and went against that foolish statement
