Q-Poll: After 'Best Weeks Ever,' Clinton Trails Carson, Rubio, Christie, Cruz

Following Hillary Clinton's smooth, mendacious performance before the Benghazi Select Committee, the verdict among the chattering class was nearly unanimous

And how is that playing out in the latest batch of polling? She's certainly pulled decisively ahead in the Democratic primary, as her remaining "rivals" aren't serious about beating her. But in a general election setting, she's stagnant. NBC/WSJ's Democrat-friendly series shows Hillary Clinton tied with Ben Carson and nursing a margin-of-error lead over Marco Rubio -- though she tops Donald Trump by a comfortable margin. Quinnipiac's latest looks worse for her:

Carson 50, Clinton 40 (-10)

Rubio 46, Clinton 41 (-5)

Christie 46, Clinton 41 (-5)

Cruz 46, Clinton 43 (-3)

Clinton 46, Trump 43 (+3)

Per usual, hypothetical head-to-head polling this far out should be viewed very skeptically. Pollsters underestimated the scope of the GOP's 2014 victory, and totally blew last night's easy victory for Republican Matt Bevin in Kentucky. More relevant are her enduringly weak fundamentals. She's at a net (-10) on overall favorability (among the major candidates, only Trump and Jeb are worse), she's languishing at an abysmal (-24) on trustworthiness, and registers at (-9) on the important metric of empathy and caring. Americans split 43/54 (-12) on whether Hillary Clinton shares their values. In the race for the Republican nomination, Donald Trump and Ben Carson are virtually tied at the top of the heap, with Rubio and Cruz pulling into double-digit third and fourth place positions, respectively. Carly Fiorinia's momentum appears to have well and truly vanished, as she's slid to just three percent support, just behind the floundering Jeb Bush, at four percent. Jeb has announced a comeback tour, promising to improve his performance at debates and convey a newfound sense of urgency.
