Exit polls in Tuesday's presidential election show that Barack Obama received a sizable majority of the votes from a variety of demographic groups.

They include African-Americans, Latinos, people under the age of 40, members of the Jewish religion, and gays and lesbians.

Experts say the Obama campaign's ability to connect with these voters and get them to cast their ballots has much to do with the effectiveness of the messaging from his state and national teams.

After the elections, political parties often analyze what was done and try to gauge its effectiveness or faults, according to Kevin Coe.

Coe, an assistant professor of communication at the University of Arizona, says it's analogous to a football coach reviewing a video of a recent matchup to see what worked and what might have been done differently.

In the political game after this general election, many Republicans are likely to reconsider what they are saying to different demographic groups and how it's being said.

"Even though this was a close election, the trajectory of some of the demographic shifts and so on suggest that maybe the messages they've been using will increasingly alienate sections of the public that you just can't alienate in this day and age," Coe says.

"And so it will be interesting to see the extent to which they really do try to shake things up. I expect some kind of power struggle in the party and we'll see what happens."
