Short answer to the OP, it really doesn't matter. Liberals see an issue they think will gin up outrage in their base (it will, because their base is totally clueless anyway) and were stung in the past by their own candidates' lack of interest in performing the duties of the jobs they so passionately pursued (there's a reason our president is known as president 'present'). Thus, they stomp and wail and bang their spoons on their highchairs, thinking they're scoring vast political points, not realizing how utterly ridiculous they look.
