I'm a Republican and I Need a Mechanic. Who Should I Choose?

This won’t be cheap…

I’m a Republican and I need my car fixed. I could go to a guy who isn’t a mechanic but says he can fix anything, a guy who says he’s a mechanic but hasn’t fixed anything, or a guy who has been a successful mechanic for over 25 years.
Who should I pick?
Lately, I think most Republicans would pick the overly confident non-mechanic or the guy who is a mechanic but hasn’t fixed many, if any, cars.
Or I’m a Republican and I need major surgery. I could select a guy who isn’t a surgeon but says he can cure anything, a guy who says he’s a surgeon but once closed down the operating room, or a surgeon who has been doing surgery well for over 25 years.
Who should I pick?
Lots of Republicans are saying we don’t like the mechanics and surgeons we have now. GOP voters are turning to those who have little or no experience, instead of finding a well qualified and experienced mechanic or surgeon. They seem to be willing to roll the dice with someone who unrealistically thinks he can fix anything (Trump) or someone who hasn’t fixed anything much (Cruz)  instead of the person who has a record of fixing things (Kasich). This doesn’t seem like a strategy for long term success.
