Most Democrats are liberal.
In general, Democrats tend to prefer more government involvement in fiscal issues, than social issues.
Democrats tend to distrust business more and expect government to keep it in line by regulating it and curbing free market excesses. They protect jobs.
Democrats are more likely to support antitrust measures and monitoring how business operates. They may be more concerned than Republicans about things like government addressing CEO salaries and if business appears to be cheating the consumer or endangering safety and well-being.
On the flip side, Democrats are more likely to assume that abortion is a personal choice, that school prayer or other religious issues have no place in government run schools and that it has no business telling someone that being gay is wrong.
Since Democrats envision an active government, they may enact measures to assure that anyone considered different is protected by not allowing individuals or organizations to discriminate against them.
Government action is necessary in order to help the family function better. This justifies many of the social safety-net programs (like food stamps) that make up the government’s public assistance network.
Democrats like the uniformity, and equality, of federal activity to the disparity produced by differing state and local government actions.
Democrats tend to embrace a more expansive definition of “family” than Republicans.
Democrats are more likely to limit gun rights.
Since Democrats see a larger role for government in society and the lives of individuals, you’ll find them working for government in higher percentages than Republicans. Most government employees are Democrats. This shouldn’t surprise anyone. It is a natural result of their ideology.
Democrats believe that governmental activity protects our freedoms. In other words, government acts so that we can be more free.
