Tuesday's revised convention agenda has Republican Fred Thompson and Independent Joe Lieberman, telling delegates about the John McCain they know.
Still, many observers will be more focused on McCain's vetting of Vice Presidential pick Sarah Palin.
Aides insist McCain knew about her teen daughter's pregnancy before the pick was announced.
Word 17-year-old Bristol will keep the baby and marry the teen dad won praise from Alaska delegates at the convention.
"That just shows all the more Sarah Palin is totally pro- life," said delegate Grace VanDiest.
The McCain campaign reportedly decided that Palin revelations would come the day Gustav made landfall.
It was Gustav that kept President Bush away from the convention in person.
Tonight delegates hear from him by satellite.
Outside, more protests were expected Tuesday, but not on the scale of day one's huge anti-war rally.
Police arrested scores of self-described anarchists, using pepper spray and smoke bombs to detain them.
