By DAN MERICA WASHINGTON (AP) — Protesters can create awkward moments for presidential candidates. They interrupt, heckle and, oftentimes, knock a candidate off track. But Vice President Kamala Harris is trying a new strategy late in the campaign to turn what would otherwise be awkward interactions into moments of energy used to rally her supporters and subtly drive her message against her Republican opponent, Donald Trump. At all three of the Democratic nominee’s rallies on Wednesday — in North Carolina, Pennsylvania and Wisconsin — pro-Palestinian protesters broke in with chants, banners, and even a whistle to criticize Harris for how she and President Joe Biden have handled the war between Israel and Hamas in Gaza.
