Trump has legitimate bragging rights: Losses in the House could have been worse, and the Republican showing in the Senate was strong. His political base is still there for him, and in many key statewide races, there for the candidate he endorsed and stumped for. His rallies are still a hot ticket three years after his initial rise. He now has a cadre of allies, like newly elected Florida Gov. Ron DeSantis, whom he basically created.
Alienating traditional Republican voters in the suburbs, of course, comes with a real cost. For one thing, it hands Democrats a constituency spread throughout the country, as demonstrated by the GOP carnage in House races all over the place.
But, for Trump’s purposes, the GOP’s strength in Florida, Ohio and Iowa suggests that, all things being equal, key pieces of his 2016 electoral map are still ripe for the picking in 2020.
