For what it's worth, I never heard any media reports about this incident involving anyone "blaming the right" for anything ... probably because it's been more than a decade since I've watched or read anything that is considered a "credible media organization" in this country.
In this case I didn’t hear anything directly either, probably for the same reason as you.
But I well remember Mayor Bloomberg himself saying about the foiled Times Square bombing attempt that (I paraphrase): maybe it was someone upset about the health care reform law.
Sure bloomy, because that makes sense.
