Arguably more successful is Abraham Lincoln. Though, it might be more accurate to say that the newly formed Republican party didn’t kill the Whig party; rather the Whig party killed itself due to not listening to their constituents (which seems pretty relevant to our current situation)

If the voters are too apathetic to what the DNC is offering, the thought of abandoning them for something that is much more popular isn’t a contradictory prospect. Having an enthusiasm problem so big that trump was able to be elected twice kinda points to the fact that people want something else.
