They program the machines to give a certain percentage to each candidate. They focus their efforts on large cities in each state, which are always heavy Democrat compared to the rest of the state. You'll notice, they hold the results of these big cities, especially in battleground state where they need to falsify the vote tallies, sometimes until dawn the next day. This is how they attempted to flip Michigan, but you cannot flip the state when you need more votes than you have people residing in the precincts. When they realize they cannot steal the state this way because of a landslide victory for one candidate, they abandon the attempt. They tried to flip Wisconsin by doing the same thing in Milwawkee and failed there too. Bev Harris did an interview with Alex Jones in which she identified their failed attempt to steal five states. What she did not mention is that, even though they failed to steal those five states, they did succeed in stealing others and running up the count in California to give Hillary the popular vote. GS himself predicted this exact outcome months before, because the real polls (not MSM) were showing a massive landslide for Trump with pathetically low turnout expected for Hillary.
