Even now, after so many words have been written about the Affordable Care Act, it is distressing to realize that had just one Senate Democrat opposed Obamacare, the law would not have passed the Senate as it did. Just one nay would have forced improvements in the law, making Obamacare far less destructive than it is today.

Many Democratic Senate candidates are now running on Obama denial. But not one Democratic incumbent voted against President Obama’s stimulus. Not one voted against Dodd-Frank’s too-big-to-fail for large banks. Not one Democratic senator voted against Majority Leader Harry Reid’s gutting of the 60-vote rule for presidential nominations. The consequences? Mr. Obama was able to pack the D.C. Circuit Court of Appeals with three liberal judges, which will make challenging his rule-by-regulation on oil and gas that much harder.

Read here from the WSJ how Democratic incumbents—from Mary Landrieu to Mark Udall to Mark Begich—are jumping through hoops in almost comic denial of their lock-step support of President Obama over the last six years.
