If you're a miner, you're most likely a Republican

Miners lean conservative according to an analysis of campaign contributions by occupation.

Verdant Labs compiled the study using US political donation data from the FEC.

For every 10 miners who donate to Democrats, another 90 will have donated to Republicans. Interestingly mining engineers side less with Republicans, 18 Democrat donations for every 82 Republican.

Within the resource sector, only oil workers are more conservative than miners.

Though still mostly conservative, forestry workers and farmers all have greater Democrat leanings.
