I find Marco Rubio and Christie have good chances over Jeb . I think it's too early to say but no body wants another BUSH as Presidential Candidate .
Rubio and Christie really aren't being taken seriously as conservative candidates.
The people who are motivated to actually appear at the primaries have been talking people like Scott Walker and Ted Cruz. There are some who are considering Carson, but most aren't all that enthusiastic about any of the choices.
The GOP is pretty much done even within conservative circles. If they can force their way through the primaries by conscripting democrats to vote in the republican primaries (which they have done in the past) - then there are people who will vote for them simply because they aren't democrats, but most people have been pretty put off by the GOP, lately.
Most of the conservatives will find an independent to vote for just to not give the GOP any ideas that they have tacit approval to continue existing.
Hillary is a sure shot Democrat candidate for POTUS.
In a simple word: no.
There is a reason why she 're-launched' her campaign. That reason is the same reason she is not electable. Her speeches have more press than guests. Her 'talks with average people' have been shown to be campaign workers for the democratic party who weren't even told they were meeting Hillary until after they were committed.
No one likes her. She is a cold, vile woman who didn't think twice about giving the order to allow an ambassador to be killed rather than blow the lid on her program to arm Syrian rebels (who later became ISIS).
She gives flat, uninspiring speeches and acts as if the world owes her the presidency.
Yes, there are lobotomized zombies who will vote for her because she allegedly has a vagina and a D next to her name - but there are many within her own party who simply won't be motivated to vote for her - or be motivated to vote against her because she is so repulsive. Her book she wrote about being the Secretary of State? Complete and total flop. Book stores couldn't give it away. Compare this to books written about Obama's campaign, about Bush, or about Katniss.
The democrats will run Fauxahantas (Elizabeth Warren) over Hillary. One of the reasons they are letting Hillary act like she's going to run is because she needs to embezzle more money out of her 'charity' and because she knows where the skeletons are buried - Hillary is a Fratricide risk for the Democratic party - she'll slaughter another strong democratic candidate who tries to step out of line by airing out their dirty laundry and quite possibly getting a court conviction on them.
Obama won by appealing to the younger voter base that grew up during the late 80s and 90s. Polling data shows that voting demographic has swung -very- conservative over the past 4 years (the product doesn't stack up to the marketing) - not in who they support, but in their views on policy. Arguably, they are more Libertarian than Conservative - but that places them more in favor of candidates like Reagan than Clinton - which is a massive swing away from candidates like Obama.
That voting demographic comprises a considerable 12 year grouping, or so, and there hasn't been sufficient time for the 'disenfranchised youth' voting pool to re-stock. Motivating them in a similar fashion to get out and vote will be hard enough to repeat even if they had another Obama. Clinton is a pasty old white hag complete with a maniacal cackle. She belongs in a shack, stirring a cauldron; not sitting in the White House. The fact she has a dried up vagina isn't going to motivate even the disenfranchised youth to vote for some kind of hope and change.
Someone like Warren is infinitely more personable (though she's even more psychotically 'progressive').
Of course, Hillary should be on trial for multiple counts of treason, fraud, obstruction of justice, etc. If she manages to dodge several death sentences, she should never see the light of day, again.
Much less campaigning to be President.
But the GOP is incompetent and won't actually prosecute her because they think that the Democrats are going to give them a reach-around next time the big blue weenie gets crammed up their rectum. That is why Boehner is meeting with Obama to try and get the trade deal that gives Obama unilateral authority to negotiate trades passed through congress.
Or... whatever it does. No one who has seen the legislation is allowed to tell us what it says and even Pelosi is against giving the President that kind of authority.
Which is why the conservatives are about to boot the GOP out of the Republican party. That - or the Libertarians are going to end up coming out of nowhere for wins in a future election cycle.
