But, since I checked before posting this, it seems a lot of others have made similar observations.
Dana Milbank at the Washington Post fills out this thought most clearly:
By their own logic, Republicans and their conservative allies should be concerned that Isaac is a form of divine retribution. Last year, Rep. Michele Bachmann, then a Republican presidential candidate, said that the East Coast earthquake and Hurricane Irene — another “I” storm, but not an Old Testament one — were attempts by God “to get the attention of the politicians.” In remarks later termed a “joke,” she said: “It’s time for an act of God and we’re getting it.”
The influential conservative broadcaster Glenn Beck said last year that the Japanese earthquake and tsunami were God’s “message being sent” to that country. A year earlier, Christian broadcaster and former GOP presidential candidate Pat Robertson tied the Haitian earthquake to that country’s “pact to the devil.”
Previously, Robertson had argued that Hurricane Katrina was God’s punishment for abortion, while the Rev. John Hagee said the storm was God’s way of punishing homosexuality. The late Jerry Falwell thought that God allowed the Sept. 11 attacks as retribution for feminists and the ACLU.
