The Hagan election is going to be decided by casual voters.I live next door to North Carolina and have family there. The State narrowly went for Romney. Kay Hagen repeated the "if you like your plan, you can keep your plan," over and over. She is seen in the State as an Obama rubber stamp. She will not win re-election. Bank on it.
The other two States, I cannot comment on because I do not know them politically.
I agree, though it will be more complex an issue than "if you like your plan, you can keep it" by my measure. Hagen will be outspent 2 or 3 to one in the end and therein will be the ballgame.
NC SBE Election Results
Primaries have a much lower turnout that general elections, and the number of votes cast in the Republican primary for the U.S. Senate seat (488,554) only barely surpassed the votes in the Democratic primary (482,369) for the same race. It will come down to swaying the casuals, the undecideds, the "I usually don't vote because who cares" crowd--not necessarily Unaffiliateds (NC's version of being registered as Independent), but people of any affiliation who either don't normally vote or who only vote in general elections. Personally, I don't think that Thom Tillis (the Republican nominee for the Senate seat) will pick up that many more guaranteed votes than he got in the primary, and I also think that a sizeable chunk (in the tens of thousands) will refuse to vote for him. Libertarian candidates always gets roughly 2% of the vote, despite not representing 2% of registered voters, and those who voted for candidates like Greg Brannon and Heather Grant (the second and third place candidates, respectively) in the primary will be far less likely to set differences aside and vote for Tillis.
I suspect that we will be heading into a close race that will be decided by the lowest common denominator. Tillis will paint Hagan as Obama's mouthpiece (the line "Kay Hagan votes with Obama 96% of the time" has already been floating around for a while), while Hagan will paint Tillis as a crooked politician (e.g. Tillis supporting legislation to allow natural gas companies to claim eminent domain to steal a person's land for the purpose of exploiting natural gas resources on that land, and Tillis then suddenly getting contributions from PACs representing gas companies, their executives, etc.). Sean Haugh, the Libertarian candidate, will likely pick up a large number of Republican votes and could wind up becoming a spoiler in the election, i.e. he may siphon just enough votes away from Tillis to ensure that Hagan gets re-elected by a narrow margin.
