SEASON FINALE: A summary of the season’s highlights begins at 8 p.m. ET, for viewers who want or need a refresher, and the two-hour live finale, filled out with lots of guest performances, follows at 9. Yesterday, the four finalists sang for the right to be crowned this season’s winner – and with Alisan Porter given the closing spot to sing “Somewhere” from West Side Story, the late advantage was in her favor. Will she be the first female winner of The Voice? Probably. But with the American voting public, you can never be too sure. Look at politics.
