Kim Strassel of the WSJ states her case:
1) Consider North Dakota. A recent Zogby poll showed 28% (you read that right) of state voters support “reform.” A full 40% said they’d be less likely to vote for Democratic Sen. Byron Dorgan next year if he supports a bill. In a theoretical matchup with Republican Gov. John Hoeven (who has yet to announce), Mr. Hoeven wins 55% to 36%. Mr. Dorgan has been in the Senate 17 years; he won his last election with 68% of the vote.
