The bill as it stands won't pass the House. Needs some fine tuning - much too long and filled with hodgepodge. Most Republicans want to see something passed. But we'll see who the real obstructionists are and who is and who is not willing to compromise when the time comes.
Some of us want the immigration bill to be over and done with so Republicans can focus on real tax reform. Now's the time if ever there was a time.
Much more than fine-tuning is required.
Border security must be achieved before any discussion of amnesty.
If you compromise on this issue, the only tax reform you will see (with millions of illegals voting) is higher taxes.
