1) Donald Trump in battleground states is doing better than Donald Trump in national polls
1b) Counterpoint even though Donald Trump is claiming to be do well in Rust Belt States, he is doing worse than past republican candidates
2) Donald Trump does not need to get to 50%+1 in these battleground states due to the 3rd party "spillover candidates"? It appears that if Donald Trump wins several battleground states it is because people did not vote for him or Hillary, but the people who did vote for those two people Donald wins more than Hillary.
2b) Note I am not going to say that Donald is going to win more vote percent than Hillary in battleground states that Clinton, but this is how he is going to win those states if he does win those states.

There is a real potential for Donald Trump to win the electoral college. Lots of things have to line up in a roll and A leads to B, B leads to C and so on but it is possible.
