California, Illinois and New York are shrinking. Texas and Florida are growing rapidly. With America's population shifting from reliably Democratic states to areas controlled by Republicans, Democrats are facing a demographic time bomb that could reduce their path to winning the U.S. House or the presidency for the long term. If current trends hold through the 2030 census, states that voted for Kamala Harris will lose around a dozen House seats — and Electoral College votes — to states that voted for President-elect Donald Trump. Democrats' path to 270 Electoral College votes, the minimum needed to win the White House, will get much steeper.

Kamala Harris and Donald Trump are both seeking support from Arab American voters as they campaign in Michigan, trying to lock down support in a battleground state that could decide the presidential race. Trump was expected to visit a new campaign office Friday in Hamtramck, one of the nation's only Muslim-majority cities. He will be joined there by Mayor Amer Ghalib, a Democrat who has endorsed Trump. Meanwhile, three city council members in the same town have endorsed Harris. The vice president began her day in Grand Rapids with a rally with other Democratic leaders. She then goes to Lansing, where she will speak at a United Auto Workers union hall.

President Joe Biden's ability to run for reelection faces crucial tests Thursday. He will be fielding questions at a highly anticipated press conference that many Democrats will be watching for signs he's up for another four-year term. And he sent his campaign team to meet privately with skeptical senators on Capitol Hill, even as two more House Democrats called for him to exit the race. The Biden campaign is laying out what it sees as its path to keeping the White House in a new memo, saying that winning the "blue wall" states of Wisconsin, Pennsylvania and Michigan is the "clearest pathway" to victory. It says there's no indication another Democrat would do better against Republican Donald Trump.
