PA: One last Romney foray for Obama to defend

BRYN MAWR, Pa. (AP) -- Mitt Romney is making a concerted push into Pennsylvania in the final days of the presidential campaign, aided by outside political groups that are spending millions on last-minute ads there to help erode Barack Obama's 2008 support.

Polling shows Obama holding on to a 4- or 5-percentage-point lead over Romney, but the trend has been in Romney's favor.

Can Pennsylvania help him win the election, or is the state once again teasing Republican presidential candidates only to see them fail?

Without winning Ohio, Romney needs Pennsylvania in his column, and he has the money to make a play for it. Unlike states with early voting, 95 percent of the votes in Pennsylvania are expected to be cast on Election Day, justifying a late attempt to sway the outcome.
