Nate Silver (over at 538) projects Paul in 2nd behind Romney by 8%
I won't go into all the methods he used and the implications (it's not a bad read tho

)
I'll just say that outside of what our own RPF members in Hawaii have clued us in on it's one of the most encouraging things I've read.
Remember % of votes is essentially 'zero sum' so shifting 8% with the conditions in Hawaii on the ground is quite doable. (also note that the projection of Mr. Silvers that I 'am referencing was the
least favorable to Paul out of the three he possibilities he presented)
As has been said it's all about ground game now, it's
Get Out The Vote and getting people to the polls.
If you know anyone in HI whom you have some pull with get them out to vote for Paul, party need not matter
