yehudayona: Can Johnson-Weld get a plurality in any state. Yes, especially this year. Most hard-core Trump supporters hate Hilary, and most hard-core Clinton supporters hate Trump. In addition, a large part of both parties, perhaps a majority, did not merely support someone other than the party nominee, but really don’t like their parties nominee.
A Johnson-Weld win can occur if: 1) many Sanders supporters decide they want the disruption (and social libertarianism) of Johnson rather than Clinton, which is increasingly likely if Trump appears not to be a threat to carry their state; 2) many conservative Republicans decide that Clinton is no worse than Trump and vote for Johnson to make a point. If at any point it becomes a race between Clinton and Johnson, or less likely, Johnson and Trump, it will greatly benefit Johnson since he is clearly the “2nd” choice of both parties.
If Johnson gets some electoral votes, and the election isn’t a landslide for either candidate (most likely Clinton), it goes to the House of Representatives which votes by state (meaning an evenly split state has to abstain), and as the 2nd choice, Johnson is probably the only one likely to end up with 26 states.
Whether Johnson is good for the Jews, or good for Israel, is worth discussing, but I believe it is definitely a possible three-way race. Remember that in previous three or four way races (1992 with Perot, 1968 with Wallace, 1948 with Wallace and Thurmond, and 1912 with Roosevelt), the third party was not drawing heavily from both parties, and if Johnson is able to draw from both parties it will be an unprecedented situation (compatible only to the four way race in 1860 which resulted in a total political realignment, not to mention a civil war).
