Senate: Democrat Incumbent's Lead Vanishes After Obamacare's Rollout

In September, Sen. Kay Hagan (D-NC) was against delaying the Obamacare individual mandate. She also led all her potential GOP challengers by double digits.

But now? The lead is gone, according to a Democrat polling firm.

Incumbent Sen. Kay Hagan (D-N.C.) is near the top of national Republicans’ target list for 2014 — and a new poll shows her lead over her potential GOP challengers has all but evaporated.

Against state House Speaker Thom Tillis, Hagan leads by only 2 points, 44 percent to 42 percent, according to the Democratic firm Public Policy Polling. She leads Rev. Mark Harris by 2 points as well, 43 percent to 41 percent, and nurse Heather Grant by 3 points, 43 percent to 40 percent.

Hagan trails physician Greg Brannon, the Rand Paul-endorsed candidate in the race, by 1 point: he leads 44 percent to 43 percent.

That’s a huge difference from PPP’s September poll, which gave Hagan leads of anywhere from 12 to 17 points against all possible GOP challengers.

Not at all coincidentally, it's Hagan who now wants Obamacare's botched rollout investigated. She's really calling for an investigation into how she survives next year's midterm.

The next shoe drop -- the corruption within the Obamacare navigators -- has not even been absorbed by the voting public yet. It usually takes a while for a government program to attract graft and corruption, but Obamacare came with both built in.

I'm skeptical of the idea that Democrats will end up being forced to back a repeal of Obamacare. But if other vulnerable Democrats are seeing slides similar to Hagan's, it could happen. If it does, Barack Obama, Harry Reid and Nancy Pelosi could find themselves desperately defending a rump Democrat caucus by this time next year.
