Unless establishment Republicans pull some convention shenanigans, Donald Trump will likely be the GOP nominee for president. Bernie Sanders remains a contender, but it is still unlikely he will upset Hillary Clinton to be the Democrat’s standard-bearer.

But what either think about the concerns for farmers and ranchers is, and will probably remain, a mystery in the short run.

There was a time when presidential candidates pursued the farm vote. But farmers and ranchers have gotten short shrift from presidential candidates in the 21st century.

That is at odds with a certain reality. Everyone in America eats, and eats quite well. Food is so abundant that it doesn’t register as a concern, and food producers are so few that they no longer constitute a viable interest group.

Trump’s website doesn’t mention agriculture specifically. Sam Clovis, Trump’s national campaign co-chairman and chief policy adviser, told our sister newspaper the Capital Press the campaign “looks at agriculture from a security issue as every bit as important as energy and border security.”

Clinton’s campaign didn’t respond to the CP’s request for information. Her website offers the vague promise to “increase funding to support the next generation of farmers and ranchers, invest in expanding local food markets and regional food systems, and provide a focused safety net to assist family operations …”

Here’s what we know based on what the candidates have said or published:

Neither Clinton or Trump like the Trans-Pacific Partnership, the big 12-party trade deal now pending before Congress and important to agriculture.

Clinton was for the pact before she was against it. As secretary of state she touted the negotiations and the prospects for a deal. She once referred to the TPP as the “gold standard” for fair, transparent trade. But once the deal was finalized, candidate Clinton dropped her support.

Her online campaign material doesn’t say what she wants in future trade deals.

As always, Trump is blunt. “The TPP is horrible deal,” Trump said of the pact. How he thinks it could be improved, we don’t know. His positions on trade are fairly general — it will “flourish,” he says.

Clinton supports the use of genetically modified crops, and mandatory labeling on food products. Trump, who eats organic at home, told the Iowa Farm Bureau that he supports the use of biotechnology in food products and opposes mandatory labeling. On immigration — a matter hugely important to farmers — the candidates occupy opposite poles.

Clinton supports a path for citizenship for illegals now in the country, Trump does not. Clinton supports “humane, targeted immigration enforcement.” Trump wants to hire 10,000 more U.S. Immigration and Customs Enforcement officers and repatriate all criminal aliens as well as everyone caught crossing the border. Clinton supports the president’s plan to give work permits to as many as five million illegal immigrants. Trump supports mandatory E-Verify screening to prevent noneligible applicants from getting jobs.

Trump has promised to reduce federal regulation, Clinton has not.

For the farm sector, it’s hard to know which is the friend.
