Tomorrow, the whole world will watch as John McCain introduces and appears with his running mate as the Republican ticket in public for the first time. The timing of the announcement is meant to achieve four key goals for the McCain campaign:
1) Keep Obama/Biden from getting the kajillion point bounce they need for the Democratic National Convention to be considered a success.
2) Dominate the weekend news cycle.
3) Generate a little excitement for the moribund Republican Party heading into their dirgefest national convention.
4) Distract us all from an important anniversary.
