‘I plan on—if I’m your nominee—winning Georgia, North Carolina, South Carolina . . . and I believe we can win Texas and Florida,” Joe Biden declared Monday.
That sounds like campaign hyperbole. After all, in the last five presidential races, Democrats lost those five states 22 of 25 times, carrying North Carolina only once, in 2008, and Florida twice, in 2008 and 2012. In 2016, President Trump won North Carolina by 3.7 points, Georgia by 5.1, Texas by 9 and South Carolina by 14.3. Even when Mr. Biden was on the ballot with President Obama in 2012, they lost North Carolina by 2 points, Georgia by 7.8, South Carolina by 10.5 and Texas by 15.8.
Still, Republicans should pay attention. Change is about the only constant in presidential contests.
Consider West Virginia, which Sen. Bob Dole, the GOP’s 1996 standard-bearer, lost to Bill Clinton by 14.8 points. Only four years later, George W. Bush won the Mountain State by 6.3 over Democrat Al Gore. This 21.1-point swing gave Republicans their first victory in an open presidential race in the state since 1928. If Mr. Bush had lost West Virginia, he would not have won the White House.
West Virginia was in play in 2000 because of factors the Gore campaign overlooked and the Bush campaign exploited. First, Team Gore ignored the 11.3% of West Virginians who supported Ross Perot in 1996; Team Bush targeted them.
Second, the Clinton administration had saddled the coal-mining industry with new regulations. The Bush campaign used that to convince more West Virginians to cross over to their side.
Finally, Mr. Bush was both a better cultural fit for the state—personable, approachable and plain-spoken—and campaigned there vigorously. Mr. Gore didn’t show up often. When he did, he came across as Mr. Smarty Pants.
The point is that big flips are possible under the right conditions. “Past performance is not an indicator of future results,” a phrase common to financial prospectuses, also applies to politics. With the exception of South Carolina, Team Trump can’t take Mr. Biden’s targets for granted.
Florida and North Carolina are purple states, battlegrounds that won’t be a sure thing for either party for the foreseeable future. Georgia’s demographics are shifting, and in 2018 Peach State Republicans eked out their closest gubernatorial victory in 16 years, energizing Democrats. The Texas population is exploding with new residents, and in last year’s midterm election Texas Republicans had their narrowest U.S. Senate win since 1978. They also lost two congressmen and 14 state legislators. These trends suggest that Republicans can’t afford to be complacent, no matter how enthusiastic the president’s Orlando, Fla., rally was Tuesday.
Team Trump must also campaign hard in Michigan, Pennsylvania and Wisconsin, each of which Mr. Trump won in 2016 by less than 1 point. Assuming he carries every other state he took last time—never a given—Mr. Trump must hold at least one of these three to win. The absence of Republican governors in Michigan and Wisconsin will make winning harder. As the Trump campaign learned in those states in 2016, it helps to have a good local brand boosting the national ticket.
There’s also evidence the president’s approval ratings are now upside down in Arizona (which he won by 3.6 points) and Iowa (which he carried by 9.4). In the midterms, Republican candidates tended to win in states where the president’s favorables were higher than his unfavorables and lose where they weren’t.
