So, of course, you didn't vote for the progressive Mitt Romney in 2012, because he was for gun control and was the original architect of 0bamacare, right?
That didn't work out so well for us non-progressives, did it?
Hey, I have a great idea: how about if we nominate an arch-conservative who might not be a natural born citizen, who isn't even liked by his own Senate colleagues, who trusted the 0bama administration enough to grant him blanket trade promotion authority on the Trans-Pacific Partnership, and who probably can't make significant inroads into the demographic groups which are necessary in order to win the 2016 general election for US President?
Or maybe, alternately, let's nominate someone who isn't a politician at all, who has a record of getting things done in the real world, whose published policy positions are eminently conservative, who has his hand on the pulse of an extremely angry electorate, and who has led the charge on critical issues from the very beginning of his campaign?
Or, as a final alternative, how about if we nominate the candidate who has accumulated the most delegates at the time that the convention comes along, and then support that candidate, even if he happens to not be your first choice, or mine?
Nah. Better to just pontificate sanctimoniously about "progressives", sit on one's hands, don't show up to vote, and be a purist to the point that the rabid progressive Democrat or the cronyist crook Democrat wins instead...
I did not, will not, vote progressive.
