Will the U.S. try to stop online gambling

[J.R.]

I can tell you laws aren't often interpreted with an eye towards naturally extending their meaning (unless you are dealing with the modern Supreme Court's constitutional jurisdprudence), so the short answer is no, unless it the law mentions something specifically about poker or uses a vague word like "gambling" instead of referencing horse racing. Laws the permit generally prohibited activities are often construed as narrow exceptions to the staus quo and strictly interpeted.
