It's Isaac versus Mitt.
Who will win the battle over the next 72 hours? The Tropical Storm or the Republican Presidential nominee?
It seems an extraordinary decision to cancel the first day of the Republican party convention just because of a storm battering Haiti and heading towards the Gulf of Mexico. It may even miss Tampa.
But there is method in the madness.
Monday was always going to be a wash-out in terms of the lineup of speakers. The big guns are due to appear later in the week, and the major US TV networks had already decided not to broadcast the day's events.
In addition, Mitt Romney and his party's top strategists knew that a storm would dominate the news agenda. It would be used by everyone from political analysts to late-night comedians as a metaphor for the Party's recent woes.
The maverick Senate candidate Todd Akin has offended millions of women. A series of gaffes from Mitt has the candidate's managers on the defensive. There has been a luke-warm reaction to Paul Ryan joining the ticket.
Late last night the decision was made. Compress the news into a dynamic three days. Surrender to Isaac.
