Hurricane Gustav has blown the presidential race into uncharted waters.
Never in living memory has a national political convention been overwhelmed by such a potentially huge natural disaster.
"One of the things we know about a hurricane is that many times they do the unpredictable," Sen. John McCain said Sunday afternoon as organizers of the convention that will nominate him for president upended their intricately scripted plans.
Gustav's political impact promises to be just as hard to forecast as its path toward the Gulf Coast, confronting Republicans with anything from a catastrophe to an unexpected opportunity to demonstrate leadership instead of talking about it.
By radically truncating their convention, at least for now, the Republicans are staging a near-oxymoron -- a political convention that could end up being free of politics and devoid of speeches. While that robs them of their nationally amplified megaphone, it also allows them to stand above the fray, raising money for hurricane victims and praying for them aloud.
McCain instructed his GOP brethren in a satellite feed from St. Louis on Sunday that the time has come to "take off our Republican hats and put on our American hats."
Brian Sullivan, a prominent Republican activist in Minnesota, said McCain's decision to scale back the convention was showing that the likely Republican nominee was willing to take a "do what's right, and things will shake out" approach, just as he did, Sullivan says, in supporting the troop surge in Iraq.
"We may not have the convention we thought we would have, but we can still show that the Republican Party is one that can respond to a crisis," said Charlie Weaver, head of the Minnesota Business Partnership and a Republican activist.
