The Rachel Maddow Show has its tissues ready; we're execting a tear-jerker of a speech from Obama tonight. Not only is today the anniversary of Rev. Martin Luther King Jr.'s "I Have a Dream" speech but it is also the first time in almost 50 years that a candidate has given his acceptance speech in a venue like Mile High Stadium.

And on the other end of the excitement spectrum there is the John McCain campaign! The campaign is confirming that a running mate has been selected and supposedly it's down to Mittens Romeny, Tim "Nice Hair" Pawlenty and Tom "Bulldog Face" Ridge. So tonight Rachel will be talking to Minneapolis mayor R.T. Rybak about Pawlenty, the governor of Minnesota, about their contentious relatonship and whether or not Pawlenty is a good choice for McCain. Oh, and we might even ask him for some bar recommendations for when we are in St. Paul next week.
