Ramesh Ponnuru warns at Bloomberg View that Republicans will be very foolish to believe that scandals are a substitute for ideas:
For the most part, Republicans didn’t campaign on impeachment in 1998: They didn’t say, “Vote for me and I’ll do my level best to oust Clinton.” Their strategy was more passive. They were counting on the scandal to motivate conservatives to vote while demoralizing liberals. So they didn’t try to devise a popular agenda, or to make their existing positions less unpopular. That’s what cost them -- that, and the mistake of counting on statistics about sixth-year elections, which also bred complacency.
Republicans have similar vulnerabilities on the issues now. They have no real health-care agenda. Voters don’t trust them to look out for middle-class economic interests. Republicans are confused and divided about how to solve the party’s problems. What they can do is unite in opposition to the Obama administration’s scandals and mistakes. So that’s what they’re doing. They’re trying to win news cycles when they need votes.
