The points that you bring up are minor compared to his conservative views. The following is from the article.

Johnson's views have been described as fiscally conservative and socially liberal[110] with a philosophy of limited government[111] and military non-interventionism.[112][113] He has identified as a classical liberal.[114] Johnson has said he favors simplifying and reducing taxes.[115] During his governorship, Johnson cut taxes fourteen times and never increased them.[116] Due to his stance on taxes, political pundit David Weigel described him as "the original Tea Party candidate."[117] Johnson has advocated for the FairTax, a proposal which would abolish all federal income, corporate and capital gains taxes, and replace them with a 23% tax on consumption of all non-essential goods, while providing a regressive rebate to households according to income level. He has argued that this would assure transparency in the tax system and incentivize the private sector to create "tens of millions of jobs."[118] Johnson supports the Trans-Pacific Partnership.

These views are the furthest thing from liberal that you can get. There was also mentioned a 43% cut in social programs to balance the budget. He is for a national sales tax on all non-essential goods. That is about regressive as you can get.

He was describe as "the original tea party candidate". Liberal is a swear word in the tea party.
