Democrats need to be very careful. When Senator McCain introduced Governor Palin as his running mate, Republicans completely knocked Democrats off their message. The Democratic Party had just come off a very strong convention and a historic speech by Senator Barack Obama. Yet the introduction of Palin created a media frenzy around her, distracting reporters from the main contest, and giving Republicans a chance to regroup and to rebound in the polls.
Tonight's debate, in certain respects, comes at perfect time for Republicans. Whatever happens, Americans will be watching Palin not Obama.
