WASHINGTON (CNN) - Is Sen. John McCain too old to be president?
Listen to some Democrats, and you'll think the 71-year-old Arizona senator is a man lost in a perpetual fog. He is "confused" and has "lost his bearings" or is "out of touch."
Listen to the McCain campaign, and you'll be convinced that Democrats are using those terms to exploit concerns that the presumptive Republican nominee is too old to effectively serve as president.
For his part, McCain tends to answer questions about his age with quips such as, "I'm older than dirt and have more scars than Frankenstein, but I've learned a few things along the way."
The first salvo of the general election's age war may have been launched in May, when Sen. Barack Obama argued in an interview with CNN's Wolf Blitzer that McCain had "lost his bearings" while pursuing the Republican nomination.
