Please tell me your three top pro-Chafee reasons why you support his campaign

Please don't include any reasons that merely show the shortcoming of any other candidate (e.g., I am not interested in hearing that you support Chafee because "Sanders is too ___ and Clinton is not ___ enough and O'Malley is just plain ___".

Also, I know that anyone inclined to respond likely has more than three reasons why they support Chafee. I'm not looking for a list of reasons (there is a campaign website which already provides that data); instead, I am looking for a prioritized list of the top three reasons (actually one reason or two reasons are fine, but I'm not looking for any more than three reasons) for why his supporters have chosen him.

Thank you.
