Here's an interesting poll: Hillary Clinton handily beating Christie, Paul and (especially) Cruz.
While there was a clear front-runner among possible Democratic contenders.
To me, there's a sliver of good news for the GOP in these figures. It's that "Unsure/No Answer" is at the front of the pack in the party's prospective primaries. Time to think out of the box. I can think of a couple of academics who might be ready for a change of scenery in a few years.
