Team Obama is certain of its hold on the Senate. One Federal Judge has placed an order, a more Obama-compliant Federal Judge may stay that order (or try to) to give the Federal Marshals DOJ cover to do nothing. Pending appeal, pending clarification, pending impact assessment, pending pendingpending ... lawyer stuff. Law vs What's Right Scenario.
At this point, Ted's excellent letter is a praiseworthy rhetorical exercise. Could go to reality. Could go to combat. Could go nowhere. This Jeh Johnson is a total Affirmative Action Nincompoop who knows at least on what side his bread is buttered. It ain't buttered by Ted Cruz.
BTW, that letter is clearly racist.
The letter itself does nothing but form a record. Records are necessary when preparing to take real action. It’s called laying the groundwork.
