As an independent voter, I do not especially care for either John McCain or Barack Obama. I wish that someone else were running on the major party tickets. Having said that, I am somewhat pleased (and also somewhat concerned) that Obama selected Sen. Joe Biden as his running mate. Biden is clear and carries himself well. However, he had a brain aneurysm several years ago, and on several instances he has been accused of plagiarism.

I phoned a first cousin who suffered a brain aneurysm several years ago. She told me that, in her case, her mathematical skills were irreversibly impaired by the aneurysm. Obama should have chosen someone slightly younger — someone with a clear health history and a healthy brain.
