SP 800-100, Information Security Handbook: A Guide for Managers (October. 2006 ), is available at: http://dx.doi.org/10.6028/NIST.SP.800 -10 0. (redirects to http://nvlpubs.nist.gov/nistpubs/Legacy/SP/nistspecialpublication800 -1 00.pdf ).
What percent of registered voters are Republican? As of 2011, Gallup polling found that 31% of Americans identified as Democrats (tying a 23-year low), 27% as Republicans, and 40% as independents (largest in 60 years).
Thanks to population changes in the last four years, if the 2016 Republican nominee maintained that non-white percentage, he or she would have to win about 64% of the white vote, according to Republican pollsters Glen Bolger and Neil Newhouse-a seemingly insurmountable margin.
