I've received press releases from several pro-immigration groups tearing in to Rubio as well as a scathing statement from the anti-immigrant Federation for American Immigration Reform. And Harry Reid has already said he won't consider a "watered down" bill. To be fair, no one yet knows the details. But the general assumption is that it will not offer much. I'm guessing it will focus on military service. Readers of this column know that I support piecemeal immigration reform measures since the political environment for comprehensive reform is dismal. So if the Rubio bill is a positive one, just not as broad as many would like, I will support it. Not so many years ago, members of both parties would come together and compromise rather than filibuster or otherwise kill every bill offered by the other party. If Rubio's bill is offered in the spirit of compromise, I will consider that a positive development.
