The RNC and convention organizers announced six more speakers for the convention overnight, all but one of them significant figures within the new generation of Republican leadership.  That one, however, will be the big story.  Former Democratic Rep. Artur Davis, who co-chaired the 2008 Barack Obama campaign and seconded his nomination at that year’s convention, will speak at the Republican convention to exhort people to vote Obama out of office:

Former congressman Artur Davis from Alabama, who officially seconded President Obama’s nomination at the 2008 Democratic convention, said on Wednesday that he will cap off a remarkable political metamorphosis by addressing the Republican convention this year — calling for Obama’s defeat.

Davis said in a telephone interview that he had been given a speaking slot at the Republican convention in Tampa later this month. Davis said he was not sure yet of the day on which he would speak.

But Davis said he planned to speak for millions of Americans who, like him, had traced a path from hope to disillusionment with Obama. After spending his entire political career as a Democrat, Davis declared earlier this year that he was a Republican.

“The one thing that I can bring to the table is to be something of a voice for that group of people,” Davis said in announcing his speaking slot.

This follows the approach from yesterday’s AFP ads, which mournfully lament the failure of Hopenchange to lead as President.  It’s a subtle and smart tactic that allows moderates to still express some kind of affection for Obama while sending him into retirement.  In its own way, it takes some of the venom out of politics by separating job performance from personality — although don’t expect the talking heads at MSNBC or CNN to give the Koch-brothers-backed AFP any credit for that.

Davis will, however, draw attention to that very concept.  He told the Washington Post that he’ll focus on two failures, direct promises from Obama that not only went unfulfilled but ended up making things worse: unifying the country and turning the economy around.  As Obama’s former campaign co-chair, he will have unique insight into exactly how Obama has failed the country, and will force the media to cover it based on the news value of his apostasy.  Investors Business Daily thinks he’ll have lots of material to use that the media has thus far ignored:

So which candidate is the press complaining about?

In a front page story on Wednesday, the Washington Post attacked Romney, not Obama, for adding “an even uglier tone” to the campaign. …

But you will search that Post story in vain for any reference to the series of bogus claims made by team Obama about Romney’s tenure at Bain. You won’t find a mention of Sen. Harry Reid’s completely unfounded accusations that Romney didn’t pay taxes for 10 years.

There’s no mention of the Obama campaign’s repeated false claims that Romney opposes abortion even in the case of rape and incest — which earned a “pants on fire” rating by Politifact for being so blatantly false.

And while it mentions that despicable Obama superPAC ad, the Post story fails to explain it was wrong on all the key facts, or mention how Obama campaign aides lied about knowing about the ad before it aired.

And has the media — other than ABC’s Jake Tapper — bothered to notice that Obama has been using Seamus the Roof Riding Dog as an argument for re-election all week?

The announcement of Davis’ slot will overshadow the A-list of the Republican bench added overnight, although I doubt any of them mind:
