Hillary does not look so formidable any more.
Those numbers look legit, despite the source. How Trump runs (and spends) can be a bit of a wild card, those less effective in Iowa and New Hampshire than in bigger states with open primaries.
As things now look, I expect Christie to bail after a weak showing in New Hampshire. Carson may be a problem, as he could finish second or third in Iowa, making him a story, and draining % away from better candidates. He also doesn’t need as much $$$ to stay active, just enough to get on ballots and in debates.
Cruz is keeping his powder dry, as is Walker. Neither wants to be any more of a target than absolutely necessary. If Jeb is near the lead, it also makes for a more compelling fund-raising pitch.
Herself, Madame Benghazi, the Cold & Joyless, is already feeling pressure from the left, as Bernie Sanders keeps dragging the dialogue further and further into the fever swamps.
Now, since fever swamps are the natural habitat of trolls and ogres, tactically this may not be a bad thing for Herself to prep for the primary campaign. But Herself has to, sooner rather than later, actually have to start ANSWERING the questions that are thrown out at press conferences, but continue to be squelched either by a quick exit, or deliberate and very obvious snubs to the one who chose to make such a dire breach of etiquette, offending every tenet of deference to royalty.
Bernie has no such aversion to conversing with the press people.
