Tuesday’s election in Georgia’s 6th Congressional District has important lessons for both parties.

The Democrat started out attacking Donald Trump and then went on to other messages. The Republican attacked Nancy Pelosi throughout. But on election eve, voters were telling reporters that health care was what they cared most about.

Karen Handel, the Republican candidate, should have been very vulnerable on this issue. Polls show that even Republicans are opposed to most of what the GOP is doing in Congress. What her website said about health care was far weaker than the website of Jon Ossoff, the Democrat. The problem for Ossoff: he had no real plan to make Obamacare better. Perhaps for that reason, he left health care out of most of his campaign ads.
