Someone wrote on this thread that Roberts is a bad candidate. Roberts has been in office for decades - he can't be but so bad of a candidate. A bad candidate is one like, uhmmm-uhmmm Akin or, let's see, oh yes, O'Donnell.
Anyway, the last time Kansas elected a senator of democrat persuasion was in the 1930s.
In a republican year, the odds of Roberts losing are small, but there is always a possibility.
An additional prediction - McConnell is going to win by 10 points and the usual suspects on this website will be gnashing their teeth, moaning and groaning, claiming that McConnell rigged the election, cheated and the democrat should have won because, by golly, only their opinion matters and their opinion is the only plausible one to think and all the others are abhorrent and unnatural.
None of them can think strategically, at all. Simple and small minded, they have no idea how controlling the Senate can enhance 2016 presidential politics. Passing a few bills that will force Obama to address and veto, can help drive issues in the 2016 race. This is one way to go over the heads of the media.
That alone makes him a bad candidate.
Plus control of the Senate will moderate candidates for the Supreme Court in the last 2 years of Obama...
