I have taken a good hard look at the electoral college map and to me it shows a very close race. If things go as expected and the normal Democratic states vote that way with the republicans doing the same this thing could go 259-259 with Ohio and it's 20 electoral votes once again deciding this election. There are a number of swing states of course, more so than the last two elections but if they vote as they have historically it will be once again Ohio that tells the tale. So, nobody is unstoppable, certainly not Obama since the Democrats lost Ohio in the last two elections. Clinton carried it twice before that but Reagan and Bush One also won Ohio.
