One aspect I find quite fascinating is the diverging trend, which puts Trump about 30% above Cruz, even though they started out quite close together. That’s about double the 15% or so margin we see in the national polls, even though I would think that FReepers, being engaged in politics, are not “last minute” deciders.
Most of us aren't wishy washy, we do "keep up" with the news, so it doesn't surprise me that most of us have picked a candidate to support and that's it for us.
