Farm and oil subsidies. Start there.
Great, let's end farm subsidies.
As for oil, you need to show any oil subsidies exist.

What are the estimates of fossil fuel subsidies in the United States?
As of July 2014, Oil Change International estimates the total value of U.S. subsidies to the fossil fuel industry at
$37.5 billion annually, including international finance. This does not include military, health, climate, or local pollution costs. These subsidies have increased dramatically as U.S. oil and gas production has increased.
Many numbers circulate as estimates of U.S. fossil fuel subsidies. This explainer details what those numbers actually represent:
$2.4 Billion: subsidies to the Big Five producers debated and defeated in the Senate in 2011 and 2012
The Repeal Big Oil Tax Subsidies Act, sponsored by
Senator Menendez (D-NJ) was
debated and defeated by the Senate for two years running, and would have eliminated $2.4 billion in annual tax deductions for the five major oil companies: BP, Exxon, Chevron, Shell and ConocoPhillips.
Although the move would have been an initial step, it’s just the tip of the iceberg. So called “independent” oil companies are hardly small businesses. Major integrated oil companies also include Occidental, Amerada Hess, Marathon, Murphy Oil and dozens of others. Together, these companies
produced 53.5 percent of U.S. oil in 2009."
