‘Blue wall’ reinforcement

None of the seven primary battlegrounds have tipped so far in one direction that either Vice President Kamala Harris or former President Donald Trump can afford to take their foot off the gas. Both candidates are scrapping for every inch of ground for a map that was shaken up by President Joe Biden’s eleventh-hour exit from the race. 

But like the rest of the map, swing states are judged on a sliding scale, with some more favorable to Trump and others more favorable to Harris. The respective campaigns have to be realistic about their chances of success so they don’t wind up throwing good resources at voters who have moved too far away from them.
