So this is interesting, even with all the trustworthiness concerns people have about Clinton she's still polling second-highest among the candidates in that category. (Ignore the headline, it's not supported by the poll, which was just "would you trust [blank] as commander in chief", not whether you want them or not.)
Percent who said "yes" for each candidate
Sanders - 38%
Clinton - 31%
Trump - 26%
Cruz - 20%
Kasich - 19%
Rubio - 16%
This isn't directly related, but I feel like Rubio looks like a 7yo boy in a suit.
