It is true she has slide since she left State, but being out of the limelight probably has a lot to do with that. But compare her to these others in the same NBC poll.
These figures only include those who approve or disapprove, but not those who are neutral or have no opinion.
President Obama 42% approve 51% disapprove minus 9
Speaker Boehner 21% approve 43% disapprove minus 22
Senator Reid 17% approve 34% disapprove minus 17
Senator McConnell 17% approve 28% disapprove minus 11
Senator Cruz 19% approve 30% disapprove minus 11
Hillary Clinton 46% approve 36% disapprove plus 10
Governor Christie 33% approve 17% disapprove plus 16
Make of these numbers what you will. But I find it interesting that everyone who was involved in the shutdown is on the minus side of the ledger. Those two on the plus are not so much in the limelight at least during the shutdown and had nothing to with the shutdown. Also note that the two people with the highest differential on the minus side are the two leaders of congress, Republican House Leader Speaker Boehner and Democratic Majority Senate Leader Reid.
Indeed, I would assume her absence from politics has a bigger impact than anything else.
PS not sure what the point is harping over the fact the guy disagrees with the article from the OP though. Seems rather pointless
sure, just like last time, as a front runner, when push comes to shove democrats chose a person with no real experience over her.
but this time her last name is guaranteed a victory.
Ironically, where Obama was able to damage her was casting her as an establishment type centrist, and himself as a political outsider. Though that clearly had more to do with competent campaigning than reality
