if they were porsches
 

if they were porsches which would they be? and why?

Kerry would be a 914.

Is it a Porsche or a Volkswagen no its both... It was whatever they needed to call it to make it to the market. See the resemblance :)

I could go on and on

Bush early 911 - Unrefined and wild just like the young Bush was

You should have made it so we can vote on more than one possibility; that's the premise of your question.

I have some views on which Nader and W would be.

Kerry's a 914 all the way. They all have rust and need tons of work to make presentable, or you can just put some new rocker covers and a cheap paint job and try to sell it off to some idiot, just like John Kerry.

Kerry's a Yugo and Bush is a Chevette.... No Porsches here...

Art,

You hit the nail on the head. No pushing from the rear here, only pulling from the front. No purpose-built engineering, and plenty of understeer. Actually, I mis-typed, they both oversteer in that they are both at the extreme of their parties.
