I'm going to take heat for this, and rightfully so, but one argument that I have heard is that the government will have to become more totalitarian to deal with the expansion of previous 'minority' groups.
As the size of these groups increases due to immigration, so too does their voting capability. They become increasingly politically relevant, and soon politicians will have to specifically target these groups, along with white and maybe black groups, to build up their constituency. Assuming (this seems likely) that each of these groups will have different needs and subgroups with different needs, the result of this will be less defined political platforms and a diminished ability for the government to do its job, as it is left currying favour with more groups than before. The left, which looks to sate political demands (esp of the 'needy') will be left making series of concessions or be stuck in a political quagmire. The right, being more pragmatic, will simply target the largest groups or crack down on voting rights to simplify the process. End result is a totalitarian state, or at least a breakdown of democracy. At this point, I feel that it would be possible for a Civil War to erupt as the government is overthrown.

Of course, this is NOT my argument, may be a poor argument, and assumes ceteris paribus- one might assume that the government would adapt better to the changing political circumstances.

IMO it's an interesting point of view, and I would very much like to see it criticised, as I am not up to speed on US politics. Maybe this deserves another thread, however.

Thanks, please understand that this isn't my view as I don't know enough to have a solid view,
