But once again facts have surfaced. We now know that Mr. Ayers hosted a fundraiser for Mr. Obama. They served for years together on a board with only a few people, and they worked closely on financial matters during those years. Does that sound like someone he barely knows?

And then we have the Iraq war. Congress authorized war against Iraq in 2002. The vote in the Democrat-controlled U.S. Senate was an overwhelming bipartisan majority of 77-23. The intelligence provided to Congress was profoundly flawed, but based on the intelligence presented, Congress voted for war. That is why those voting for the war included John Kerry, John Edwards, Hillary Clinton,and — yes — Joe Biden.

Yet Mr. Obama, who was in the Illinois Senate at the time and thus had no vote, opposed the war. He says that this shows his superior judgment, and that those voting for the war, like John McCain, lack the judgment to be president. But his vice presidential pick Joe Biden voted for the war, and Mr. Obama says Mr. Biden has the judgment to be president. How do you reconcile that?

And finally we have the surge. Mr. Obama opposed it, saying it was doomed to fail. Yet the troop surge has succeeded brilliantly, and all but the most dedicated diehards admit it. Now Mr. Obama acknowledges that it succeeded, but does not admit his predictions of failure were wrong. How were they not wrong?

These actions have made a pattern. Mr. Obama has changed his position on numerous occasions, cannot explain why he has done so, and yet his campaign expects us to believe that he never changed his mind on any of those issues.

He must think we’re stupid.
