It's illogical. That a party has the power doesn't mean they have full control over everything that happens in a particular state. There are different interests competing for one another, budgetary considerations, the need to deal with the opposing party on many issues. Unlike Republicans, the Democrats aren't all in lockstep. Consider what's happening on Congress now with Democrats in control. The margins are so slight, they are constricted from doing things they promised. Besides, what's in a national platform may not apply in a state.
In contrast, there is NO Republican platform for 2020. They have no solutions for inflation, high crime, high gas prices (except to pump oil, which we're doing and to drill, which is up to the oil companies on thousands of unused leases). All they do is make up stories about critical race theory and gay people, which solves nothing. It just makes people hate people.
