The various interest groups largely hate each other, or at best barely tolerate each other. The only thing you can do to "unite" them is to promise them freebies, or special treatment.
The different interest groups never seem to realize that their interests often conflict with each other, and that special treatment for one is at the expense of another.
Yes you are correct, but its a shame we are so poorly lead by people who make the Left out to be a nearly unstoppable monolithic political coalition, “them libruls.”
