"Comfortably" is a stretch... especially when both candidates are in the 30s.
Up by 8% with only 11% undecided isn't comfortable?
The Independent support is sure to drop.
In Maine, where an independent got 21% of the vote last time? Where an independent was elected governor in 1994 and 1998? I wouldn't be so sure about that.
But what was the level of support for the Independent months prior to the vote the last time? I'm asking because I honestly don't remember, not to prove a point. I just know that support for Independent candidates generally seems to fall as a general election approaches in this country.
