Just because the two groups each serv(ic)e corporations doesn't make them the same party. Even though all corporations strive to make money, there are some rules that allow certain businesses to thrive (perhaps at the expense of others) and other potential rules that would turn the tables. As an example, tough monopoly legislation can be considered anti-corporate, but smaller/medium businesses need it to compete with the big dogs. Also, the farm bill and other related subsidies are designed to keep the cost of producing food low (and reliable), but fruit growers typically do not benefit in the way certain other foods (including meat) are catered to; as such, people don't tend to buy as much fruit as they would on an even playing field. This matters to corporations, because certain ones profit while others struggle.
I respect the point that from the perspective of consumers and individuals, Republicans and Democrats are both heavily disappointing, but I have a hard time not going a step further and finding the Republicans positively atrocious.
