The White House has another web page providing “four principles to the President’s common sense proposal.”
The important thing to note is the final word in that sentence: on its face, this is a legislative proposal, not a set of actions the President intends to take without constitutional or legislatively delegated statutory authority. This is very different from his recent rhetoric, which has been interpreted as a threat to act unilaterally if Congress does not legislate.
The text of “the President’s Proposal” is confusingly written in a way that implies both a legislative proposal and unilateral action. If the President does act unilaterally, without statutory authority delegated by Congress, he would provoke the constitutional crisis that his opponents have forecast. Read as a proposal, however, the text is not nearly as extreme as the President’s own statements suggest it to be.
