Not a big deal considering that his mother is still alive....she was born in 1912 and is 103 years old
While the voters of Arizona are free to choose whomever they want, I would point out two things:
First, it's pure insanity to have
anyone to stay in power for that long - he was first elected to the Senate in 1987, so he's been here 28 years already. He was a Representative for four years, so he's got 32 years in active politics. John McCain doesn't have a monopoly on good ideas after all nor is he irreplaceable.
Second, his mother may still be alive and he may live to be over a hundred too. So what? Even the sharpest mind declines with age. Even if John McCain is mentally sharp as a tack today, will he be tomorrow? Or will he simply be an invalid that's fed mild farina and steamed carrots and told who to vote for?
