The SPLC has documented an explosive rise in the number of hate groups since the turn of the century, driven in part by anger over Latino immigration and demographic projections showing that whites will no longer hold majority status in the country by around 2040. The rise accelerated in 2009, the year President Obama took office, but declined after that, in part because large numbers of extremists were moving to the web and away from on-the-ground activities. In the last two years, in part due to a presidential campaign that flirted heavily with extremist ideas, the hate group count has risen again.
