It is very early days in the race for the GOP presidential nomination, but at this point I believe my favorite is Governor Scott Walker of Wisconsin. His accomplishment in pulling the fangs of the WI public employee unions is simply huge.
As a lifelong government employee I worked at various times for a county, three states (CA, OR, TX), a territory (Guam), the federal government, and a community college district. I believed then, as I do now, that civil servants should not be allowed to unionize.
When the university faculty of which I was a long-time member unionized, I refused to join and paid the mandated-by-law "in lieu" fees instead. Political contributions of public employee unions effectively "purchase" the allegiance of the legislature which then raises their pay and benefits.
This behavior is a massive conflict of interest that should be banned, a view with which Gov. Walker agrees. Curbing the power of public employee unions may not be the sexiest issue facing a new president but it is certainly one of the most important for the future of our nation.
