the job itself is just an executive job, but the president is also the leader of his party and the one who sets the legislative agenda. With Obama elected for another four years, you can expect Obamacare to be solidified, probably 1 more liberal justice, a more progressive approach to social issues and welfare spending, and more of the class divisiveness we saw in the first four years. That won't ruin us, but at least it will put more obligations on the books and grow government, at most it will move the political conversation leftward.
