That is a serious ticket. What is worse: it may, actually, elect Trump.
How so? I would think that the ticket is more likely to attract dissafected Republicans than Democrats.
I'm guessing ag believes that Hillary will need those Trump protest votes to win.
Ag has this weird belief that moderates and establishment Republicans are going to become Democrats in the future and the Sanders people will become Republicans, and that Hillary Clinton voters would just as easily vote for moderate Republicans. I feel like he only sees in black and white, so all the evil Trump and Sanders supporters get lumped into the other party, while the nice moderate heroes become Democrats.
Moderate is a crappy term because the new Republican Party in being nationalist will be far more moderate on a number of issues than it was during the Bush and Tea Party eras.
I actually agree with ag, but with a slightly altered trajectory. Most Sanders Democrats who are actually on the left will remain Democrats for a long time. Sanders independents might flow to Trump in the right circumstances. However, it is true that I see a good number of neo-conservatives and neoliberals flowing into the Democratic Party in opposition to Trump. This will make life rather difficult for Sanders people who probably hoped to inherit the earth post Clinton. I have a feeling who the next nominee for the Democrats would be in this scenario and lets just say, 2020 is going to be fun and painful for ride for, well most everybody.
Nationalist Conservatism has a long history of co-opting socialism on a limited basis. This was very much in vogue in the mid 19th century when the threat of Revolution threatened the established order in Europe. It was also noticeable as late as with Nixon and his co-opting of liberal policies to weaken the Democratic coailition. It was also rather true of the early Republican Party as well, which had nationalist economic policies and also a large Progressive wing. This will take decades to come to fruition and probably generational change from either Y to Z or some other future generation. It is not as crazy as sounds on the surface, if you consider multiple historical examples from pre-1980.
