From Krugman's latest column:

Today is the last day to sign up for Medicare Part D, the prescription drug benefit. It appears that millions of Americans, confused by the array of competing plans or simply unaware of the cutoff date, will miss the deadline. This will leave them without drug coverage for the rest of the year, and subject to financial penalties for the rest of their lives.

President Bush refuses to extend the sign-up period. "Deadlines," he said last week, "help people understand there's finality, and people need to get after it, you know?" His real objection to extending the deadline is probably that this would be an implicit admission that his administration botched the program's start-up. And Mr. Bush never, ever admits mistakes.
