One more thing, you can not just look at the numbers in

Hillary/Obama case.

Just half month ago, Hillary's win to nomination is like sun set. Her lead over Obama was at least double-digit in almost every state.

Now, she virtually tied with Obama now. Trend is going against her. Her trend line has been going down while Obama's going up. Two lines crossed over yesterday.

If the trend does not change fast, Hillary would most likely lose nomination.
