2. SketchUp is one of the greatest free CAD packages ever put on the market. The free version has no limitations and it provides one of the simplest 3D design interfaces I've ever seen. Even if you've never done any CAD work or 3D modeling before, you can have some really nice presentations put together in minutes.
Bundling in political economy is a type of product bundling in which the product is a candidate in an election who markets his or her bundle of attributes and political positions to the voters. For example, a political candidate may market herself as a centrist candidate by ensuring she/he has centrist social, economic, and law enforcement positions.
The key to a political machine is patronage: holding public office implies the ability to do favors (and also the ability to profit from graft). Political machines generally steer away from issues-based politics, favoring a quid pro quo (something for something) with certain aspects of a barter economy or gift economy: the patron or boss does favors for the constituents, who then vote as they are told to.
