She did not win handily by House standards. She's a horrible fundraiser. She underperformed Obama in a McCain-friendly district. She had to be 100% bailed out by the DNC.
She beat Jeb Bradley in a huge upset in 2006. She won again by a comfortable margin against Bradley despite supposedly being "vulnerable".
I mean, no one could be vulnerable in a state Obama dominated in so much...
And in terms of fundraising, you don't need a ton of money to run statewide in New Hampshire.
Then why did the national party have to spend 2.5 million dollars for her to keep her seat?
New Hampshire doesn't have any indigenous media markets, does it?
Probably not. I remember seeing ads for Sununu and Shaheen on WBZ, a Boston network.
