As the presidential campaign continues, albeit with the field effectively narrowed down to three, the positions of those candidates on the question of raising the federal minimum wage becomes more telling.  Last month, all three remaining ‘main-stream’ candidates verbalized their support for hiking the threshold to different levels, but where are they this month?  Democratic front-runner Hillary Clinton has evolved her thinking on the issue – initially supporting an increase to $12, she recently said she would sign a federal $15/hour minimum.  Her challenger, self-declared Socialist US Senator Bernie Sanders has long been consistently supportive of the highest minimum possible regardless of its economic impact, even going so far as to file a federal $15 minimum wage bill in 2015.  On the Republican side (if he is still a Republican this week), presumptive nominee Donald Trump initially advocated a small increase in the current $7.25 wage floor, saying he was “open to doing something about the $7.25 per hour minimum.”  This week however, on a Sunday morning talk show, declared he’d rather leave the issue to the individual states.   They want to follow in the footsteps of the nation’s 3rd President, Thomas Jefferson who said: “On matters of style, swim with the current; in matters of principle, stand like a rock.”  Principles, what a concept!
