Because there are 5 people and they are running neck and neck.
That’s not the situation in todays primary. Kasich should have been asked to leave. Same as the next one that cannot get the desired number of delegates. Of course that would only apply to those where people actually got to vote for candidates in the states. No game playing with delegates.
Do you disagree with the idea that the winner should have the support of at least half of the party?
Shouldn’t the “winner” have the support of 100% of the party?
Winner has the support as the wishes of the voter has spoken, but that basic concept by the establishment is ignored as primaries where all can vote is not what the establishment wants, nor their talking hacks and trolls.
I am speaking objectively of what will happen in the next primary, if you make it a rule that a majority is not needed. Then you will have a split along geographic and ideological lines and end up with multiple candidates with 20% constituencies.
The guy who gets the nomination should be the one who can convince a majority (at least) to back him. That’s the way it has always worked. For good reason.
After a nominee is chosen, then, yes, the entire party should support him. That is less likely if your rules are that a nomination can be won with only a plurality of the votes. The guy with 22% support who has “the most” and wins will have a hard time getting support from the other 78%.
