At least two protesters were removed from a rally for President Barack Obama here on Sunday after they interrupted his speech by shouting from the bleachers. A few moments into Obama's address at the University of Cincinnati basketball arena, a man seated in the upper rafters stood up and began shouting down the president about abortion while holding an upside down sign reading, "This Moral Wrong Should Never Be A Constitutional Right" The crowd of 13,500 drowned him out with a chant of "Four more years!" and the incident forced the president to stop his speech. The man continued shouting until five police offers hauled him out of the arena. When Obama began speaking again, another man on the other side of the arena tried to shout him down again, but was quickly escorted out. "These might have been some Tennessee Titans fans who were mad about the Bears beating them really badly today," Obama joked, before resuming his speech. Obama's Sunday evening rally was the second-to-last time he will campaign in this state, which both he and Republican Mitt Romney view as crucial to winning the election on Tuesday.
