I've been trying to put a tradesport ticker on my page. You know how to do it?
Glennbeck.com has one , you could look at the source for their page...
As for the validity of Tradesports calling elections inside the US , you must know that the majority of betters are Europeans and they are getting their info from sources like the BBC , Reuters and CNN International ,, all socialist all the time networks. I'd put a bet down on maintaining house control..
Not sure how to do it with Tradesports, but intrade allows you to do it, and there are instructions on adding a ticker on their website.
