He won in 2008 and, again, in 2012 by using election fraud.
You mention “demographic disaster”; could you be more specific?
I don’t believe the 2008 victory needed fraud; McCain was a horrible candidate, and the media completely neutralized Palin.
The demographic disaster is the low number of American voters with any ideological link to the Founding Fathers; many have foregone children, and the masses imported to replace the lost generations are nanny-state socialists. The date floated out there by the media (probably to prevent a reaction or panic) for the point where “white Americans are no longer a majority” - 2050 - is absurd to anyone with eyes. My children were born over a dozen years ago, in a hospital in a “white” part of NJ, and the maternity ward had two white babies, two black babies, one Asian/Oriental baby, and ten Hispanic babies. It seems one out of every five Hispanic women I see on the street (or in the workplace) is pregnant, while less that one in every two hundred white women are in the same condition.
Anyone who sees a maternity ward, playground, or schoolyard knows that 2020 is a much more likely date for this event.
There wasn’t any electoral fraud. If there were, it was minimal.
