But when you actually click on them, they do not work, you get some other site, or a window saying that link does not exist or something similar.
This is what I am saying, the links on Google that I found do not take you to any PUMA PAC, or any PUMA08 political site or anything connected to the group of Hillary supporters.
The other direct links FReepers have provided with the actual PUMA NAME seem to work - thanks to all. But you can't get there through Google. At least that is my experience.
