Romney has spent little time in Pennsylvania, but the campaign increased efforts there in the final days of the presidential race -despite the fact that the state hasn't supported a Republican presidential ticket since 1992. 

President Obama is expected to win the state by about four percent, according to Pennsylvania race tracking.

"I don't think there's any objective evidence that Mitt Romney has been able to expand that [electoral] map. I mean, the thought of him going into Pennsylvania and winning Pennsylvania is just not based in reality," Obama Deputy Campaign Manager Stephanie Cutter said on MSNBC's "Morning Joe."

While Democrats have called the act desperate, the Romney camp will at the very least be able to say it campaigned hard in swing states. 

"The people of America understand that we are taking back the White House because we are going to win Pennsylvania," Romney told a raucous crowd in the suburbs of Philadelphia.
