Haven’t figured out yet if I’ll blog about tonight’s RNC “keynote speakers” as their acts unfold, or just wait until tomorrow, when my blood pressure has subsided. If Tampa’s already getting to you, I’d suggest a strategic diversion into something sensible like the Washington Monthly‘s new piece on colleges that deliver real value.

Here are some midday news treats:

* Darrell Issa complains that media have assigned “second string” to exciting news events of Tampa, while saving stars for trifle of huge storm hurtling towards New Orleans.

* I haven’t written about this yet because I keep thinking more facts will emerge, but what we know already is astounding: twin killings designed to protect bizarre and well-financed conspiracy based at Georgia’s Fort Stewart to take over base and assassinate the president.

* James Fallows supplies Common Cause brief in constitutional challenge to the filibuster.

* Conservatives abuzz about “mystery speaker” for final night of Republican Convention: Could it be Palin?

* Politico speculates about assortment of Bush veterans, defeated pols and former lobbyists–plus nearly all the Veep List finalists–said to be under consideration for Romney Cabinet.

And in non-political news:

* Isaac officially a hurricane as it nears Gulf Coast.

Back after I figure out why my jaw is suddenly swollen.
