Based on the comments I saw then the only possible conclusion one can come to is that if Trump were governor of Wisconsin then he'd have raised taxes. to cover the roadwork and the deficits and what have you. That's not conservative.
Don't forget the Canadian Universal style Healthcare he supports, or supported, or kinda supports, or whatever his position is now. Be interesting to see how he plans to pay for that. All well and good to bash Obamacare, but the last plan I've actually heard from him was his love of socialized medicine. But nah, Trumpsters don't want to hear any policy specifics. Just anger and bombast. I wonder if they've even noticed that Trump is already backpeddled so far on amnesty he is pretty much right where the other candidates are. Secure the border and kick out criminals is his current position, that is no different than pretty much all the rest. The rest, apparently, can stay if they are good people according to "the Donald"
We now have the collapse of Detroit and the chaos in Baltimore to compare against the future results in Wisconsin. Democrat governing versus Republican governing.
Regarding infrastructure spending, it's possible that a medium-term strategy was to free up the funds by cutting back on union entitlements instead of raising taxes. Once the cash flow settles down from the change, then the money can be allocated to road repair.
This kind of strategy might have been a non-starter in the past, because nobody would get past taking on the unions first the way that Walker did.
