McCain is apparently going to focus on Pennsylvania, a State that no Republican has won in years, he thinks he can put up a fight if he wins here.
"John McCain's efforts to snare Pennsylvania appear to be faltering despite a major commitment of his time, leaving him with a narrower path to the magic number of 270 electoral votes needed to win the presidency.
McCain is targeting Pennsylvania in hopes of winning at least one state that voted for Democrat John Kerry in the 2004 election. With 21 electoral votes, a victory there could offset possible losses in smaller states captured by President Bush in the last contest.
Yet by any number of measures, McCain's prospects are dimming. An aggregate of public polls shows Barack Obama with a double-digit lead in Pennsylvania.
Registered Democrats outnumber Republicans by more than 1.1 million, about twice the gap in 2004, state figures show."
