You have either forgotten the lines of dumbass kids in line at registrar offices and then or simultaneously at voting locations ...(same day reg, same day vote)
Or have you given up (it's only 3 delegates), she'll get her money from the Montana residents through their "other" state residences, contacts, bundleres.
[And... what's the difference between a female socialist or male socialist? To the socialist party... NONE!!!!]
No, remember that Montana is a fairly reliable Republican Presidential state. Since 1968, it has only once gone Democrat (in 1992), and that only because Perot took a huge % of the vote (26%). Bubba Clinton won with a plurality of just 37.6%, which was less than GHW Bush, Sr’s national percentage where he lost. It swung back to Dole in 1996.
Even the execrable Socialist ringer, Willard, beat Zero by 14%. Trump will probably expand upon that figure.
