Whare the differences between Clinton and Sanders on immigration?

Hillary Clinton supported the Democratic bill presented by Ted Kennedy for comprehensive immigration reform. Sanders voted against it not because he did not like the main part of the bill but because he did not like one of its provisions about temporary work permits for Mexican workers. So, I would say the difference between them is that Sanders is willing to make the perfect an enemy of the good and Hillary Clinton is not.

Accomplishing anything in Congress requires compromise and accepting some parts of a compromise that one does not like.

One is trying to give away the country to immigrants, and the other is trying to also buy them lunch.

They are both weak on border security. Honestly I think the only mention it because the have to.
