Is that how it works - just a straight campaign for eight months with no primary?
The big guy's the only (D) candidate in the primary, so he automatically advances to the general election.
Same with the guy who's the only (L) candidate in the primary.
There's two (R) candidates on the primary ballot, so that's a contest.
Think "Massachusetts" here, reversing the (D) and the (R)s, and you get the idea what it's going to be like; that there's two (R) candidates running against each other in Bellevue doesn't mean any more than when there's two (D) candidates running against each other in the Bay State.
Other than, of course, that in Nebraska the vote counts are honest, no playing games.
