Clinton 335 (70%)
Sanders 145 (30%)

Clinton ahead by 190.

1. How many of that 335 are delegates who can change their minds? nt

[George II]

2. PLEDGED DELEGATES!!!!!!!!!!!!!!!!!!!!!!!

If I included those who "can change their minds" (and they won't), it would be 747-168.

4. None. That count is 883-232

3. Fantastic

5. It's actually 8.2% Clinton, 3.6% Sanders, 88.2% undecided.

4,051 total pledged delegates.

6. Bernie would need to do in the north what Hillary is doing in the south.

Which is highly unlikely.

7. Yuuuuuge!

9. Hello President Trump

Y'all should get used to the way that sounds

[George II]

10. Are you advocating for Donald Trump?

13. Don't be obtuse

I think Clinton will be a regrettable candidate that loses the election for us.

11. I don't see these summary stats at the link.

They have pledged delegates and superdelegates grouped together. And I'm not sure what they include. For instance, Sanders is winning Colorado. That could mean 60+ more delegates for him, if it is not included in your post (and I don't think it is). So that would put Sanders at roughly 200 pledged delegates from these primary or caucus states thus far, and Clinton's "ahead" number would be less. Something like C-350, S-200. That's good for an insurgent candidate, if it's true. MA will likely split roughly in half, so it will be 400 vs 250, just from these contests.

I've forgotten the pledged delegate counts from IA, NH and NV. So I can't add it up right now. But BIG states still to come down the line: California, New York, etc. And very progressive states like WA and OR.

I hate having "superdelegates." And I hate RED states giving the most corrupt Democratic candidate for president we've ever seen "victory" headlines. This situation totally sucks.

12. My OP, as noted in the subject, included ONLY pledged delegates.

As for superdelegates, they have been part of the nominating process for about 30 years. That's the way it is. Democrats accept that as part of the nominating process.
