Barney Frank has always been my favorite Congressional Representative; I had the pleasure of being his constituent for a while in my life, and I miss that time.
If his bill passes (and, of course, it's a huge underdog), I will seriously consider playing online regularly again. Not because I won't play online if the game is illegal, but rather because fully legalized and regulated online poker will be so lucrative that it will be too difficult to pass up.
Similarly, if I didn't dislike California so much (in large part because of the poor public transit in most Californian cities) and happened to live there, I'd play in the legal local card rooms.
There are some people who are going to play poker only when it's fully legal, and those are the fishiest. I just need a huge overlay to persuade me. If the game isn't a full-on donk-fest, I can't make enough to justify the time. Legalized online games could yield hourly rates like those on Cake and Pacific in the hey days. That'd be tough to ignore, even if taking money from the clueless is starting to make me sick to my stomach.
