Hillary Clinton has demonstrated she has no respect for the rule of law. She supports a pathway to citizenship, which isn't the worst thing in the world, but I highly doubt she'd support defunding sanctuary cities, she'd support the Dream Act, and she'd try to give amnesty where she can.
The rule of law doesn't really factor into what policy proposals are.
Defunding sanctuary cities would not matter at all if there's a pathway to citizenship. The DREAM Act is a pathway to citizenship. Again, I don't understand what Jeb is offering that the Democrats aren't on this issue.
