For general discussion and debate. Possible talking point: Obama to address race and Rev. Wright:

An aide to Obama, whose speech will be delivered at a historic building across from Philadelphia's Liberty Bell at 10:15 a.m. EDT (1415 GMT), said the speech will have a strong personal element. Obama worked late into the night on Sunday drafting it...Of particular concern is the uproar over comments by Rev. Jeremiah Wright, who served as the pastor at the Chicago church where the Illinois senator was a member for 20 years.

What do you expect from this speech? Will it indeed quell concerns about Obama's connection to Wright, or will this controversy doom the junior senator from Illinois's nomination?

On the flipside, is Rush Limbaugh's Operation Chaos -- wherein he's encouraging Republicans in Pennsylvania to re-register as Democrats in time to vote for Hillary in that state's primary next month -- now a mistake? Regardless of Hillary's polarizing nature, won't Obama, as a result of these Wright revelations, now be much easier for McCain to beat in November?
