Update 2012 Convention

TAMPA, Fla. (AP) -- Republican officials abruptly announced plans Saturday night to scrap the first day of their national convention, bowing to the threat of Tropical Storm Isaac as it bore down menacingly on Florida.

"The safety of those in Isaac's path is of the utmost importance," tweeted Mitt Romney, his formal nomination as presidential candidate pushed back by a minimum of 24 hours from Monday night to Tuesday.

The announcement was made as delegates and other convention-goers flocked to the Tampa Bay area by the planeload for what had been scripted as four days of political pageantry and speechmaking with a purpose - to propel Romney into the fall campaign against President Barack Obama.

SEE YOU ON TUESDAY.........KEEPING YOU UPDATED ON THE CONVENTION.
