The "Vote" option is more complicated than the writer is making it out to be.
The United States uses an electoral rather than a popular vote process. Democrats have so concentrated their efforts into the Urban areas, abandoning rural counties that they have really hurt themselves on the national elections, as well as the House of Representatives. The only way around this would be a "change" election, where the populace is sick of the Republicans again (like in 2006 and 2008) and the centrist 15% of the country flips to the Democrats again. Or the Democrats could have another charismatic politician come up from the ranks again.
This person would have to be someone that people would be "proud" to vote for, regardless of minor policy differences.
The Senate is a bit of a different animal and I could see it swinging back to the Dems in say 2020 or 2022.
To get an idea of how bad Democrats, with this excessive concentration, look at this map:

click the "zoom out to full map" and you'll see the entire country. Cities with large populations, say 1 mil or more, are by and large Democrat strong holds. Rural areas are Republican strongholds, nearly without exception.
Democrats have to excite the rural voter to win national election, or the Republicans have to put forward a weak candidate. Republicans' have to speak to the middle class nationally, breaking into the urban centers, or the Democrats have to field and weak candidate, for them to win.
In 2016 democrats fielded a weak candidate and Republican's fielded a candidate that spoke to "some" of the issues that middle America felt had been ignored during the Obama administration. Trump played the Map in a bombastic fashion. Clinton played to the base and secure urban centers.
