Thanks - I usually try to get info by reading the article, but this was nailed down by the post you referred me to. Not likely to get a veto-proof number of votes...
They might try to attach it to something they know won’t get vetoed. That’s what Bill Frist did with the bill to outlaw online poker using the same money laundering justification. He attached to the Port Security Act in the middle of the night (literally) the day before it was voted on.
