One of the common Republican arguments against Donald Trump was that he could not win the general election, and that he would lose by such a landslide that he would damage the Republican party.
This is a lie. Most of the panic about Trump is from American traitors who fear that Trump will win.
Now RealClear Politics reports that Trump leads Hillary Clinton in its average of 5 current polls.
It is hard to imagine Ted Cruz, Jeb Bush, or any other Republican candidate leading the polls at this stage. I think that it will eventually be clear that Trump has the best chance of any of them to win the Presidency.
