It's probably just me, but I really don't like giving room on the Op/Ed pages to elected officials. Fundamentally, the press should act as check on governmental power. If the President wants to do an interview, let him sit for an interview. If he wants to do a press conference, let him do a press conference. If he wants to give an address, let him give that address -- so long as the address itself is covered as news.
Giving the sitting President room to muse on the opinion pages of the nation's newspapers is downright silly. The President wields the world's largest megaphone. When he farts, citizens of the world perk up their ears. The WSJ would better serve the nation's discourse by opening its pages to quieter voices further from the halls of power.
