The potential upside of a great Obama presidency is enticing, but this country faces huge problems, and will no doubt be facing more that we can’t foresee. The next president needs to start immediately on challenges that will require concrete solutions, resolve, and the ability to make government work. Mrs. Clinton is more qualified, right now, to be president.

We opposed President Bush’s decision to invade Iraq and we disagree with Mrs. Clinton’s vote for the resolution on the use of force. That’s not the issue now; it is how the war will be ended. Mrs. Clinton seems not only more aware than Mr. Obama of the consequences of withdrawal, but is already thinking through the diplomatic and military steps that will be required to contain Iraq’s chaos after American troops leave.
