Make it an issue of interference vs. non-interference.

Fiscally, Republicans believe that the government should stay out of the economy for the most part and let people work things out for themselves. Democrats believe that the government can and should be used to help regulate things and give the economy a kick-start if the need arises.

Socially, the Republicans are more inclined to have the government be used to enforce people to act a certain way for the good of the rest of society (and that's a horrible phrasing but it's 3am here and I can't think of anything better), while Democrats are more inclined to go "eh, do whatever you want, it's not other people's problem."

So if even that needs summing up, Republicans want the government to interfere more on social issues while Democrats want the government to interfere with the economy.
