*** A team from Symantec registered 124 domain names with various misspellings of the candidates' names and attracted 21,000 hits over two months ***

So on the average each phony site received 169 hits over two months, or fewer than three hits per day. Wow, I can see how that would turn a national election.

Security companies like Symatec are notorious for putting out alarmist crap like this to drum up sales of their software. I'm surprised you were that naive.
