Former President Trump is narrowly leading Vice President Kamala Harris in the critical swing state of Michigan, according to an AARP survey released Thursday. Trump leads Harris with 45 percent support to her 43 percent among likely voters in the battleground state, while 8 percent said they would support a third-party candidate. However, in a head-to-head match-up, the findings show Trump and Harris tied at 48 percent. The poll was commissioned by the AARP and was jointly conducted by the Republican polling firm Fabrizio Ward and the Democratic polling firm Impact Research.
