How long can Jeb survive with under-10% polling and poor debate performances?

[heatmaster]

Dudeabides and this author are of the many few hold-outs for Jeb Bush, the reason is, we recognise a thoroughbred when we see it.
Let's look at the line - up.
Bush, brand-name recognition,  a proven track record. Florida.
Carson, too nice and a antidote to Trump.
Christie, has been marginalized by Bridgegate, his manner is too loud and grating.
Fiorina, shrewd and a savvy political operator and a healthy antidote to Hillary fatigue,  not to be underestimated.  Also she's a woman.
Graham, sadly not going anywhere.
Huckabee, too holier than thou.
Jindal,  had possibilities.
Kasich, to much of an insider and as Dudeabides alluded in his/her submission,  a self promoter.
Perry, dropped out.
Rubio, Young, energetic and has a good manner.
Santorum,  yesterday's news.
Trump, the less said about him, the better, he's a motor mouth on energizer batteries....going on & on.
Walker, had potential,  still might,  but wouldn't bet the farm on such a scenario.
My money is still on Jeb & I'm keeping the faith😊
