Why hasn't Eric Holder filed lawsuits against states that have legalized pot?

Because the Obama administration has decided not to enforce the federal ban on marijuana. It's a violation of the Tenth Amendment, anyway.

Unlike drug use policy, immigration policy is assigned to the federal government by the Constitution, which is why suing Arizona is justified.

Edit: I disagree. If Republican administrations can pick and choose which corporate regulations they choose to enforce, President Obama should be free not to enforce the federal marijuana ban.

It doesn't say in the Constitution that drug enforcement is a duty of the Federal government, therefore it's a state right.

sturdy question. If he wins the wholesome against AZ what effect will that have on state and local rules that have been handed granting sanctuary to illegals? What approximately states and localities that legalize pot while there are federal rules banning it? it quite is a can of worms.

He is too busy crushing states who are trying to stop illegal immigration.

He is too busy rapping the US economy
