(1,168 posts)Some might call what you're engaged in cherry-picking--looking for polls that fit the outcome you want.
The Ipsos/Reuters and Morning Consult polls (a) are not the most recent polls and (b) are internet polls with as-yet unproven track records.

The USA Today poll is more recent.
It's interesting that the two polls you chose are the ones that consistently have been leaning toward a Clinton over Kasich win. The only other pollster that has reported a Clinton win over Kasich since January was CNN, in a single poll.
