After doing some preliminary research on the 2016 Republican field about their positions on subsidies I'm left with the conclusion that Ted Cruz is the only reliably anti-subsidy candidate. Even Rand Paul has a questionable record on this subject.
Was there another major Republican candidate (they must have announced at some point) that has consistently rejected subsidies or made a plausible argument that his or her position has changed after making the mistake of promoting/voting for subsidies? Another valid answer would be one that finds an example where Ted Cruz promoted or voted for subsides.
The definition of subsidy would include any payment of money to a specific industry or company not directly linked to the business of government (ie private defense contractors, road builders ect.). Some common forms of subsidies supported by Republican candidates are crop insurance programs and energy subsidies. As Bobson pointed out, some of the "subsidies" I'm talking about are actually tax exceptions or credits that benefit a specific industry or segment of an industry, rather than an instance of the government transferring funds directly.
