Walker is drafting Trump's rear wheel like a Tour de France rider in a stealth tuck being towed through the peleton by teammates.
Trump blasts big holes in stuff like issues (and his reputation) and Walker silently passes through after him without much scrutiny. I'm liking the stealth. He will crack the throttle open a bit when we are closer to the primary.
Walker would be perhaps the only guy in the republican field (well, the serious republican field) who is equipped for the office.
Unions have something to fear in Walker. Rogue nations have something to fear in Walker. Baby merchants have something to fear in this guy. Its enough to make a Goldwater conservative actually harbor some hope for the country.
