Yeah, I think there's plenty of evidence up there already to show that Carson is most definitely a fringe candidate. He doesn't stand a chance at winning the GOP nomination, anyway, since he is African American and no matter how his quirky and extremist views appeal to the right wing fringe of the party, they'll never nominate a black man.
The suggestion that Scott Walker isn't a fringe candidate is, well, laughable. He's at least as extremist in his social policy as Ted Cruz. Rubio blows in whatever direction he thinks it will take to get votes. There are times he's fringe, depending on the issue, and who his audience is. Huckabee wasn't fringe last time around, but his rhetoric this time, the typical "Christianity is under attack" and "We've got to take America back" is reconstructionist in origin, and that's fringe. But Huck has no billionaire in his back pocket to underwrite his campaign. I think he'd have won the nomination in 2008 if he hadn't run out of money right before the Texas primary. Jeb Bush is also not fringe, and he does have the connections to big money, but the traditional, mainstream Republican politics that the Bush family represents is at a decided disadvantage in a Republican primary these days. Whether Fiorina is or not doesn't matter, she isn't going to be a factor. The candidates who have both money and a following are Ted Cruz and Rand Paul, and they are both right wing nut case extremists who don't stand a snowball's chance on a hot stove of winning a national, Presidential election.
Been waiting a long time for the "goods on Hillary" to come out, whether it's Benghazi, or her emails, or the alleged tax issues at the Clinton Global Initiative. The GOP has anticipated her candidacy for a long time, and with all the money they have, and all the effort they've put into it, if that's all they've got, they might as well just skip 2016 and go on home. After 13 investigations, the best they could do was come up with dubious testimony from British-paid contract security which was contradictory and unreliable. Basically, a lack of resources to provide the extra security that was requested was due to them being committed in Iraq at the time, a move made by the previous administration. As one local politician put it, "The Republicans' presidential chances will go to Benghazi to die." Either the Republican campaign strategists who have been working on this for a long time have come up with nothing of substance, or they are the most incompetent boobs in the political world. Hillary has already packed away about a quarter billion, and will likely raise three quarters before it is over, will have to spend little of it in what will be a relatively easy primary, and will come away in 2016 with an electoral victory about the size of Obama's last one, and a double digit popular vote percentage margin. And that's regardless of who the Republicans run.
Interesting, in these polls, to note that Fox news is actually reporting a GOP Congressional Disapproval rating that is only one point below CNN, and higher than the other polls.
