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).
Neither Cruz (26%) nor Rubio (28%) receives the support of a third of these Republican voters. Itâs possible that those numbers could change over the next few weeks, but it shows that support for Trump isnât limited to just a third of the GOP, but seems to include almost one half of it. Among Republicans overall, the poll found that 49% favor Trump, as do 47% of conservatives in that same three-way race.
