THE KAMALA HARRIS BOOM-AND-BUST CYCLE. If the polls are right, support for Vice President Kamala Harris, the new Democratic nominee for president, is booming. After months of President Joe Biden trailing former President Donald Trump in the RealClearPolitics average of national polls, Harris now narrowly leads Trump. The last six polls in the average show Harris ahead. Although this is exactly what Trump’s pollster predicted would happen in the immediate aftermath of the Biden-Harris switch, it is still disheartening for Republicans.

How happy are Democrats and their allies in the press? Consider this, from a longtime contributor to MSNBC’s Morning Joe on Wednesday: “Watching the VP, it was mesmerizing in the sense I’ve never seen a rally like that, either on TV or in person. And watching it, you could just sense the power in the all — and it was the power of joy, the power of laughter, the power of hope for the future.” That’s happy.
