Ahhh, you missed the point.
The DNC (that should be the SDNC -Socialist Democratic National Committee) is, one, not supposed to side with any one candidate during the silly.. Err, primary season and, two, not be so bloody blatant when they do it. The emails revealed that, as we put it, the "fix was in". Now if Mrs. HRC was expecting the left of her party to vote for her, she will likely be disappointed the night of 8 November, 2016, when ballots are counted with thousands, possibly a couple of million, write in votes for Senator Sanders for president. That number could cost her the election. Now, of course I'm encouraging all my Democratic friend (yes, I meant "friend") to do that, since I'm a Republican and we tend to vote a straight party ticket even if we have to hold our noses when marking the ballot for "The Donald".
As for correcting someone's use of English, we on the Western side of the Atlantic Puddle (I live next to the Pacific OCEAN), kicked the English out of the Colonies some 200+ years ago, and we stopped speaking or writing your language in favor of American, where we have a "sense of humor" (not "humour"), we watch programs on our televisions (not "programmes on our telly"), and we only have 2 major political parties, not the dozen or so you have to contend with. "Math" is an acceptable contraction for "mathematics" according to "The Webster's New World Dictionary". But, of course, our friends to the north in Canada, have messed up your language beyond repair (and everything has to be in both English and... Ahh, French). Have a word with Ms. Windsor, she's still the Head of State for Canada. No, we don't bow to royalty, only the current inhabitant of the White House, the Big Zero.
However, I do have one English title behind my name, BOFH and proud of it!
