Okay, I can see that. Hillary is certainly a safer choice than Obama; we all have a pretty good idea of what kinds of policies, issues, and conflicts would likely arise under her Presidency. I can understand someone picking the devil we know over whatever is behind door number three. She’s still my third choice out of the three remaining candidates, but yes, I can understand why someone would put her on top of that list.
But with all the dogpiling on Clinton's campaign, her tactics, her insistence on staying in the race, it's important to remember that there are significant numbers of people who think that she's the best choice available and have some enthusiasm about her. That doesn't mean you have to agree with them (I don't).
