While margarine traditionally does contain trans-fats, my understanding is 
that today most of them don't.

In order to make a fat solid at room temperature, you need to have the long 
hydrocarbon chains line up with each other. This allows them to get together 
more easily and lowers the melting point. This can happen either with 
saturated fats (no carbon-carbon double bonds), or with trans-fats 
(substituents on the double bonds located across from each other). Naturally 
occurring unsaturated fats (i. e., with one of more double bonds) are always 
cis - meaning the substituents are next to each other, putting a kink in the 
chain. This kink means the chains can't line up easily, and the melting 
point is higher.

So - naturally occurring solid fats, like butter and animal fat, are mostly 
saturated. Liquid fats (oils) are mostly unsaturated. Trans-fats don't occur 
naturally - they're made in a factory. Presumably companies which make 
margarine without trans-fats have simply substituted saturated fats for 
them, as it's hard to make the fat solid otherwise.

BTW, the original use for trans-fats was in Crisco.

Your chemistry lesson for the day -

When trans fats are banned entirely is that going to mark the end of
margarine?  I won't buy it at all because I loathe it but am pleased to
hear it confirmed that it's not healthy anyway.
