Yes -- it is an eighteen-point lead. 49-31. But that is still less than 50%, and the rules of the map so show such. Hillary Clinton is absolutely not going to win West Virginia.
Donald Trump will probably end up winning West Virginia about 60-40 in a binary election even in a landslide by Hillary Clinton resembling one of Eisenhower in the 1950s... West Virginia is now about as solid R in Presidential elections as any state can be, and it isn't simply a rejection of Barack Obama anymore.
So if Clinton were replaced with Joe Manchin, West Virginia would look like Kentucky rather than Pennsylvania?
What does the 7 in "18/7" indicate? 18 is the difference between 49 and 31, but what about 7.
