The fact that she's within 10 points speaks a ton to her competitiveness on GOP-turf.
Not really. It speaks mainly of her name recognition. Most of those undecideds and a few of her supporters in this poll are that way because they don't know enough about the other guy to say they'd vote for him. If an election were held there with a quickie one month campaign to let the electorate be somewhat informed, I'd expect based on this poll that the result would be something like:
R - 54 %
Clinton - 44%
Other 2%
While that would be the best Democratic performance in Kansas since 1976 when Carter got 45%, I doubt she would do that well with a longer campaign that included a chance for her negatives to go up
