Atrios was right the other day -- wingers have a rage addiction. So here we have Dick Cheney's cabana boy outraged that Inauguration Day falls on a Sunday this year. That means Obama is being sworn in on January 20th, in a private ceremony, and they'll be a public ceremony on the 21st. Just like Eisenhower did it.
The 20th Amendment to the Constitution set January 20th as the official inaugural date. Because January 20, 1957 fell on a Sunday, President Eisenhower took the oath of office for his second term in a private White House ceremony.
But to be fair to Christie, Eisenhower was a Republican, which obviously makes all the difference.
