I'm glad Tancredo is pushing on this. This is how you get something that is more satisfactory. You really push the envelope and then when you do reach a "middle ground" it's more in line with what you want. This is what the lefties do. They start out with something very radical and then when a "middle ground" is reached it's still more left than it is actually middle. They are excellent at this strategy and that is why American politics continues to creep leftward.
Also, I share Tancredo's fears. What to do with the illegals here should come after the Southern border is secured. You know what will happen. Guest worker program will go through and in the average American's mind it's over. Just what the politicians want. Then border security and enforcement will be forgotten about.
That is why Pence's program is enforcement first!
