Certainly not a terrible result for Republicans - Clinton certainly isn't invincible like some on here would like to believe, though it's an uphill climb.
She is the only one with a favorable rating at or above 50%. In fact she is the only one with a favorability rating even close to 50%!
The Republicans are going to need someone with the political skills of Barack Obama to beat her in the general election should she be the nominee. Who could that be?
Ronald Reagan is no longer available.
It's partially just a consequence of her being the only one with >90% name recognition. If Christie had the same name recognition as Hillary Clinton, he'd be at 50% favorability too! Obviously, once the campaign gets started, some of these other candidates will build on their current name recognition, and the GOP nominee, whoever he turns out to be, will have name recognition comparable to Clinton by Election Day 2016.
Not to say that that nominee's favorability will match Clinton's on election day, but your 1-to-1 comparison of the favorable number at this point seems pretty silly.
