Because there is an essential difference in the way we operate, and the way that the Obamanists and Clintonistas operate.
We can surely make mistakes; but we have a moral compass, they do not. We are committed to serving the Constitutional values the Founders passed down to us; committed to serving the interests of loyal Americans; committed to protecting America. These are purposes utterly foreign to them.
The public record of the Clintonistas & Obaminsts goes way beyond anything that can be excused by mere mistake, by even stupid mistake.
We are arrayed against people who have openly embraced policies that absolutely required a failure to protect American interests. That was demonstrably their intent; demonstrable in their own repeated pronouncements.
And if the same happens in 2018 and 2020 we should hold the President at the time to the same accountability.
