As Donald Trump and Kamala Harris feverishly chase undecided voters in the final stretch of the presidential campaign, millions of people in battleground states are being served ads on Facebook and Instagram from an obscure page calling itself “The Daily Scroll.

After stops this week in Michigan and Pennsylvania, Kamala Harris continues her tour of battleground states with several events in Wisconsin. At 1:20 p.m. ET, the Democratic presidential candidate will be at an event in Milwaukee.

These are the promises Trump and Harris have made to voters in the run-up to the November presidential election.

The pace has been frenzied because of the unusually compressed timeline, with the current race only taking shape after President Biden dropped out in July and Ms. Harris officially became her party’s nominee in August.

Vice President Kamala Harris has made lofty promises on issues including abortion, gun policy and immigration.
