That Obama was well-received at the liberal-friendly school, of course, was expected, particularly after embracing same-sex marriage last week. But his reception nonetheless represents a telling contrast from the one his opponent, Republican presidential contender Mitt Romney, received Saturday when he delivered the commencement address at the evangelical Liberty University in Lynchburg, Va. Both schools are representative of each man’s political base – for Obama, college-educated women and youths, for Romney, socially conservative Christians.But while Obama’s reaction was enthusiastic, Romney’s reception felt polite. The president’s speech rallied supporters already dedicated to his cause; Romney simply tendered a peace treaty to men and women who view him warily. Some students at Liberty, after all, were worried the GOP’s putative nominee would be booed.
