A really excellent discussion on why people make the right-wing partisan vote. This quote sums it up nicely for me:
Why, then, do right wing partisans ignore this evidence and continue to support policies that are patently dysfunctional? I believe it is because, having stated a position, based on either their own family values or those dictated by their religion, they are loathe to change their minds and declare that they have been wrong. And so, following Festinger, the disconfirming evidence causes them (or at least many of them) to dig in their heels more deeply.
Another element operates as well. Right wing positions are more frequently associated with Protestant evangelicals and with traditional (Reagan) Catholics. Often the leaders of these groups (e.g. television evangelists, sinning priests) epitomize the opposite of the stated values. But both of these groups embrace forgiveness, absolution, being born again. Other groupsâ..atheists, non-fundamentalist Jews and non-fundamentalist Protestantsâ..do not have the option of absolution; they make firmer demands on themselves and are oppressed by their superegos. Note the ‘pass’ that non-combatants Bush and Cheney received, in comparison to Gore and Kerry who volunteered to serve during the Vietnam War. Note the forgiving attitude toward to Sarah Palin, with her sinning family, which would never be afforded a comparable Democrat. “What we profess is importantâ..not what we have done”.
