TAMPA, Fla. (AP) - The Republican National Convention is Mitt Romney's show today as he delivers the most important speech of his presidential campaign and one that will introduce him to many television viewers.
Romney will be grasping for an advantage in a race that could scarcely be any closer, according to the polls. As part of that introduction, Romney appeared prepared to discuss his Mormon faith in more direct terms than usual.
That direction was signaled last night in remarks by running mate Paul Ryan.
In remarks yesterday to the American Legion in Indianapolis, Romney reaffirmed his intention to expand the armed forces.
President Barack Obama was also doing some politicking yesterday, imploring young people in a crowd of 7,500 in Charlottesville, Va., to register, vote and make sure their friends do as well "to close the gap between what is and what might be."
