So perhaps a simpler way of putting the conclusion is that the Republican Party is motivated by a general philosophy while Democrats are motivated by specific policies they want to achieve.
This is also the source of so much hate toward Republicans spouted by Democrats. It's not uncommon to hear about Republicans who "vote against their own interest". However, voting against one's own interests is a radical and amazing thing to do. If everyone who held significant privilege and power voted against their own interests we might have a more equitable world.
