Democratic Primaries

Any people pushing the "if people do not nominate my candidate, I'll vote 3rd party" or "if people don't nominate my candidate, I'll leave the party" should be summarily ignored. If Democrats fell for this, they would see it every 4 years, and the entire party would be built around not majority rule, but minority vote butthurt. If whiny sore losers want to take their balls and go home, or do whatever, I say let them. We are, and must, be a majority rule party. If a group of people cannot convince a majority of Democrats to vote for a nominee, how are they going to convince the General Electorate?
