Anger is no substitute for reason.
The pathway to getting your way in politics, is convincing more and more voters to your side.
I saw an analysis recently (and I have shown my own) stating Republicans make up 25-30 percent of voters. So if Trump is favored by 30% of 30% it means his supporters represent just 9% of the electorate.
Other analysis and polls have shown that Trump (and Cruz) fare the worst against Hillary or the other democrats.
So to me at this time, all the rancor over Trump is much to do over nothing.
Who would have admitted a few weeks ago that national security would be the hot topic of the race?
We still have a lot of topics, like healthcare, abortion, homosexual rights, race relations, taxation, etc.
