If the Republican convention had an ordinary purpose, it could have ended after Monday night, their first night. They nominated their candidates for President and Vice President. They did that early to give themselves a week to file the paper work by September 1 — the first state deadline for filing their presidential candidate and electors. The Republican ticket will not carry Delaware anyhow, but it would be embarrassing to miss that deadline.
In a normal convention, the Republicans would need a little time for the platform. They didn’t bother for 2020. They just adopted the 2016 platform. Got that done on Monday night, too, without deleting the criticisms of the “current president.”
A normal convention serves as a commercial vehicle for the Presidential ticket and the party as they go through the process of nominating a candidate for President, a candidate for Vice President, and adopting a platform. In 2020, the Republicans chose a different route. After Monday night, the Republican convention has only one purpose – to serve as a commercial for the President and, maybe, the party. You can’t really call it an infomercial, though. They lie too much for the convention to pass for information.
