The referenced Pew study is even more interesting: http://www.people-press.org/2015/01/08/the-politics-of-finan....

Some correlations I haven't seen before. The most secure voters were 3x as likely to vote as the least secure. Preference for democrats was about the same for every category of security, but preference for republicans was 3x higher among the most secure (with the difference coming at the expense of other/not sure).
