Huh?

More self-evident stupidity — Steven G. Calabresi, McCain supporter and co-founder of the Federalist Society, argues that Barack Obama is too young to be president.

The Constitution says a person must be at least 35 years old to be POTUS, and Obama is in his late 40s. However, Calabresi argues that since life expectancy is longer now, “35” should be adjusted up.

In 1789, the average life expectancy of a newborn was about 40 years, compared with about 78 today. A lot of this was because of infant mortality, but in 1789, even the average life expectancy of every man who reached age 18 was only about 47. This suggests that at best a 35-year-old age limit in 1789 might have functioned then about the way a 55- or 60-year-old age qualification would function today. On this account Obama may be old enough to drive and buy a glass of white wine, but he has a way to go before he can run for president.

But the possible human life span hasn’t changed much. Our second POTUS, John Adams, was about 91 when he died. That made him only a teenager in dog years, btw. Next?

Others on the legal left, such as U.S. Supreme Court Justice Stephen Breyer, argue that in choosing between different interpretations of the Constitution, we should select the one that will produce the best consequences. This method too suggests that Obama should be understood to be constitutionally barred from serving as president by reason of his age.

Here comes my favorite part.

We have had three presidents out of 43 who were younger when they took office than Obama would be on Jan. 20, 2009: Bill Clinton, John F. Kennedy and Theodore Roosevelt.

This is bad? Are we making sense yet?

All of them committed serious rookie blunders because they were too young.

As opposed to older guys who screwed up their entire administrations.

I don’t know how old Calabresi is, but I say he’s too stupid to be writing op eds. Or to be left alone for more than ten minutes at a time, for that matter.
