Ok, Gara, Tuck and Drummond are beholden to teachers and government employee unions every bit as much as some conservatives are to oil companies. But any similarities ends here as oil companies give while teachers and unions take; its worth noting that without the former the latter would hardly exist. An income tax back in the day funded a very austere government. 
I will say this, that prior to oils 900 million payment to the state years ago the democrats where prominent; when there wasn't a lot of money to spend. Not to say the conservatives were good stewards with our wealth, but it would have been worse with democrats at the controls. This is clearly evident in the house spending bill and properly rejected by the senate.
