Three plus hours later, we have some additional information as the Republican votes are counted and caucuses report. Cruz still takes TX and OK, no change. Trump adds VT and AR, for a total of seven wins at 10:30 p.m. Pacific Time. New is Rubio's win in MN. Only Alaska remains to be called for the GOP, and with 30% of the vote reported, Trump leads Cruz in AK by only 1.5%.
Rubio just won his first state caucus - MN - which will undoubtedly encourage him to stay in the race. This is bad news for those Republicans who wanted to beat Trump, good news ironically for Trump.
Cruz won at least some delegates in 9 of 10 states reporting, all except VT. Trump won delegates in all 10 so far reporting, and is ahead in #11 - AK. Rubio won something in 7 of 10.
Clinton won seven states, Sanders four: VT, OK, MN, and CO. I'm sure Sanders is more than encouraged as I doubt he expected he'd win that much.
People write about a divided Republican Party, although the Trump sweep belies any suggestion of balance between the two sides. On the other hand, Democrats are truly split into a populist/socialist (white) sub-party and a progressive (non-white) sub-party, the former voting for Sanders, the latter for Clinton.
Given the time difference and the closeness of the two top finishers, we may not know the Alaska outcome until morning.
