Hillary has had 600,000 votes cast for her during this primary season that Trump. Might not mean much, other than 600,000 more people came out to support Clinton with their votes than came out to support Trump.
Clinton has the Democratic machine behind her. Trump is heavily drawing upon independents and disaffected Democrats.
In other words, if Trump had the Republican machine and his base Hillary wouldn't have half the votes Trump did.
"in other words" and "if" is just conjuncture and speculation. Fact is Clinton got more votes in the primaries so far than Trump.
Clinton is winning a hell of a lot more of her party than Trump is because she has the machine behind her.
While Hillary gets 70%+ of the vote in Southern states Trump gets even more votes than her with less than 60 or even 50% of Republican voters.
With party support Trump would obliterate Hillary.
