I doubt the Clinton campaign could have had as much of an impact with the same strategy. The Republican Party is fortunate in that it has a limited number of constituents:

- white

- Christian

- rural

- guns

- lower and upper class

The upper class votes on taxes, so that is an easy one.

The rest are relatively easy to target.

The Democratic Party tries to capture everyone else, which is more people but hugely diverse. There’s hardly a single message (or single digit number of them) that resonates universally.

Identifying someone as Republican gives your clear signal for targeting if you want to get out the base, as Trump did.

Identifying someone as Democratic means they could care about a huge range of things, but you don’t know what.
