It's it's utterly fair criticism of Sallow's claim that Obama was supposedly opposed to a law that (a) he signed and (b) his lawyers vigorously defended before the court. Obama supporters can't have it both ways.
I get your point, but I am only in partial agreement.
Pres. Obama's TRUE objection to the NDAA was the GITMO component. But if he also objected to the provisions we are now discussing, he still couldn't responsibly veto the law that funded the military.
Where the criticism you make of Sallow's position has more logical persuasive power is found in the fact that the Administration sure did defend those provisions in Court..
Personally, I am happy to see it. I am no fan of Pres. Obama, but maybe (it's possible) he simply grew a bit in the job, and came to belatedly see that, as the President and Commander in Chief, he really did need those tools. So, he dropped his prior opposition and decided to do the right thing and change his mind.
If that's what happened, then props to the Pres.
