Growing up, every time there was a close football game, I got to hear Frank Gifford or Dan Meredith exclaim how a tie is like kissing your cousin. (My initial reaction was "which one?" some of my cousins were pretty damn cute.)
At this stage in New Hampshire, it looks like Bernie's playing for a tie - roughly 2 point spread for the last 2 months, and within 5 points since August.
The sad news for Bernie fans is that's not good enough - at this point it's dialed into everyone's expectations that New Hampshire's Sanders' back yard, that he should win - it's no longer an "upset".
