Stardock has released Political Machine Express, a free version of its US political campaign strategy game. PM Express is similar to its big brother in that it puts players in the role of campaign manager. This scaled back version has players working strictly for Obama or McCain during 21 weeks (primary to general election) as they try and get those sweet 270 electoral votes and become el presidente.
For those interested in a heftier experience, Stardock has a lovely Perot-friendly chart detailing the differences between the Express version and the $20 version of The Political Machine '08 on its site.
