Not worthy of comment.
If, as you say, he's gotten his way every time he's demanded tax cuts
He has. Look it up.
If the President were to lean on them, say by calling for permanent tax cuts, loudly and often, that would make a tremendous difference
Done. Time and again. Where were you?
Contrary to opinion, the President doesn't rule the Senate. Liberal Republicans stood in opposition of making them permanent. The President's pressure, fancy footwork by the House in the bill, and Americans burning up their phone lines made the Libs cave to temp cuts. Supposedly we now have a (barely) conservative majority in the Senate, whereas before it was only a Republican majority. We'll see how that affects the ability to make these cuts permanent.
I find it a waste of time to pressure the President on policy he is aligned with us on. In this instance, working WITH the President against Liberal obstruction in the Senate will yield greater reward. I save pressure against the Prez on issues I do not find him to be in agreement with, such as immigration.

It doesn't matter if you don't want to comment. It's the truth.

He's been calling loudly and often for permanent tax cuts? Here is an FR Archive search on the subject, and there are only two instances referred to therein where he called for making the tax cuts permanent. One was from his SOTU address in January (which of course included a hodgepodge of issues for that call to get lost in), and the other was from the previous September. (Compare that to his numerous calls for having a constitutional amendment defining marriage)
When, since the November election gave him his new mandate, has he called for making the tax cuts permanent? Has there even been a single instance of that since that time?
