Never under-estimate the power of a plumber.
Yes it was the plumber's from Poland that was going to be the under-mining of the British economy, employment and immigration system.
Now it is Joe the Plumber from mid-west America that is going to be McCain's saving grace. McCain is out there for Joe - in his tax policies, in his employment policies, in his health policies. At the moment McCain's world is revolving around Joe the Plumber.
And obviously a vote for Obama will mean the end of Joe the Plumber's hopes and dreams (the "American dream" no less).
Now I assume McCain knows that there are a few million Joe's out there that want to own the plumbing business that they have worked with for all of their lives. I hope all the Joe's are receiving royalties for the use of their image. If they got $1 from McCain every time he mentioned them, they could forget about buying the business and just retire comfortably now.
So a vote for McCain is a vote for Joe. A vote for McCain is a vote for a genuine war-hero that looked like a big sookie-baby because his feelings were hurt. A vote for McCain is for the man who made a blooper on the debate and was heard to exclaim a loud "Huh?!?" when he got caught out.
Gotta love politics :-)
