According to this editorial, Obama never paid for security or other costs related to his campaign visits in New Hampshire.
In a response to this newspaper and a letter to Portsmouth, Obama campaign officials said they had no role in making security decisions, so the campaign should not be expected to pay. After employing that non-sequiter, the campaign directed local officials to the Secret Service, suggesting that federal taxpayers might help defray the burden placed on local taxpayers.
Remember, these are political campaign events. As I’ve pointed out before, refusing to pay for these forces local taxpayers to make an in-kind contribution to that campaign to cover the costs of partisan political activity. It is an argument that makes sense but that in the past was met by Obama supporters who demanded to know why I wasn’t bitching about Romney’s visits.
