>> Very difficult for a third party candidate to win <<
Sure, agreed in full.
But a 3rd partier CAN derail somebody they don’t like, the way Perot derailed GHW Bush. So if Trump really despises the “liar” Cruz as much as he was indicating today, maybe DT would try to derail Cruz just for spite.
And not only that:
If Trump could run as an Indie and thereby hand the election to Hilary, I’ll bet Hilary and Bill would gladly attend Don’s next wedding in Palm Beach!
I doubt Trump would want to spend his own money and devote the time to run as a third party candidate after running the gauntlet of the Rep primaries. And then there are the problems associated with getting on the ballots in each of the states. Not going to happen.
