In a civil war, electricity, public transportation, civil order, food supplies, and sanitary services are among the first thing to go. People in the rural areas can tough it out. People in the big cities are going to have it rough. The longer it lasts, the more house cats, pigeons, and rats will be eaten. It was not a civil war, but if you want an idea, watch some of the videos depicting the siege of Leningrad on youtube.

Maybe, Maybe not. In the Russian Red/White civil wars, the Reds controlled the cities and decimated the countryside.
It depends on the level of conflict and who controls the armed forces.
Modern cities are very vulnerable. But with a military actively engaged to protect them, they can maintain services.
All the predicates to a Civil war are important to what actually happens.
If Conservatives control the Military and the left rebels in the cities, we win.
If Liberals become in charge of the military, and the rural areas rebel, Conservatives likely lose.
If the military splits, everyone loses, but Conservatives might come out on top.
