I think that the point of the article was to illustrate that many voters pick a candidate for reasons unrelated to politics.
In fact, I think a major portion of the electorate does this.
Republicans, by about 80%, chose "national security".
Dems, by something like 87%, chose "charisma". (!)

Last night I saw a "man on the street" segment on FOX. The guy with the microphone had apparently asked people what they wished for in 2008.
The first woman answered:
"Bring the troops home, end the war, stop terrorism"
I was gobsmacked. We've all heard the Dems whining that they "aren't as good as Republicans at boiling their message down to 10 words or less". Well, this woman just did it...in just 9 words she stated the total unseriousness of the Dems' approach to this election. (And I bet she would have chosen "charisma" in the first poll!).
