This election is about ending the siege upon freedom for Americans living in the USA as we are on the brink of being overrun. Nobody knows what that would feel like, except for those who understand that it’s been under siege for more than just a few consecutive years. These people will know when it’s happened if/when it does, while those who won’t will end up being in the way because they’ll be unable to lead or follow. There is still time for them, however little.
THAT is the sole reason that Trump is running away with this primary.
He was keen enough to identify the number one issue of the American people, then boldly enter the race with an ironclad promise to totally eliminate that problem from our lives.
The rest of the field then played 'catch up' and 'me too' politics, when they realized they'd incorrectly positioned themselves, vis a vis, the chief concerns of the voters.
Unfortunately for them, the American people know real leadership when they see it, and are in no mood to accept substitutes.
