Because, while speaking to California donors about how some people vote in PA after 25 years of dissilusionment, Sen. Obama said "cling to guns and religion", instead of "cling to issues like guns and religion", which was obvious given the context that he was talking about voting patterns, Sen. Clinton and Sen. McCain are trying to paint him into a corner based on a mis-speak.

Set aside the comparison with the Tuzla mis-speak.

His record and oppinions are clear.  He was clearly not being condescending.  Yet his words snuck out of a private fundraiser get clipped and truncated and twisted into a ridiculous attack.

See the 2004 interview here, he talks about votting on hot-button issues starting at minute 11:

His book, "The Audacity of Hope", has a whole chapter on Values.

I'm sure Sen. Clinton is aware of all of that, yet she's bent on the personal destruction of Sen. Obama as a way to get the nomination.  Any
other fellow democrat, in any other primary, would have defended his competitor against the acusation of the opposing party.  But Sen.
Clinton is instead circulating right-wing talking points.

Of course, hopefully we won't hear anything from former Pres. Clinton on this, because he pretty much said the same thing as Sen. Obama, arguably in a more artful way.

And painting Sen. Obama as the 'less american candidate' is not helping either.

If Sen. Clinton is trying to win the Dem nomination as the candidate of the gun-toting church-going hot-button-issue voters, she might have another thing coming.  She might need another drink.
