Both chambers of America’s Congress may flip in November

AMERICANS WILL elect 471 federal officials in November: 435 members of the House of Representatives, 34 senators, a vice-president and a president. These contests are overshadowed by the impending rematch between President Joe Biden and Donald Trump, his predecessor, which will be pitched as a struggle between democracy and autocracy (and amplified by a projected $3bn in campaign spending). Seven months of this promises to be wearing.

Cast your eye down the ballot, however, and something exotic is in the offing. At the moment, Washington is divided by the thinnest of margins. Democrats control the Senate by just two seats out of 100. Republicans control the House of Representatives by five out of 435 (a margin that will shrink to four once Mike Gallagher of Wisconsin retires next month).
