Romney was campaigning and fundraising as his party readied for him to officially become its nominee for president. Republican delegates to the Republican convention will begin the roll call vote to officially nominate Romney on Monday, which could allow him to accept the GOP nomination earlier in the week than has occurred at previous conventions.
Republican officials said the formal presidential nomination process would begin earlier in part because of concerns about supporters of Ron Paul, one of a number of Republicans who challenged Romney during the primary, could seek to disrupt the roll call. Officials were also discussing the impact of Tropical Storm Isaac on the convention.
Ahead of the four-day GOP gathering in Tampa, Fla., Romney has sought to refocus his campaign on the economy after a week dominated by comments Missouri Republican Senate candidate Todd Akin made about rape. Akin said in an interview that victims of "legitimate rape" can biologically avoid pregnancy, prompting Romney and other top Republicans to call on him to leave his race. Akin rejected those calls.
