A majority of Trump voters believe the Obama administration spied on Trump and his aides during the 2016 presidential campaign, according to an ABC News/Washington Post poll released on Wednesday.The poll, which surveyed just over 1000 people in April, shows a sharply divided country where political affiliation in large part determines how Americans understand the news. For example, while 64 percent of Trump voters believe Obama spied on their candidate’s campaign, only 10 percent of Clinton voters believe anything of the sort. Trump lobbed the allegation in an early March tweet, and so far, he and his administration haven’t been able to substantiate it. The House Intelligence Committee, which launched an investigation into the matter, also found no evidence the wiretapping happened.Additionally, the poll found that a majority of Americans, at 56 percent, believe that Russia tried to intervene in last year’s U.S. presidential election and that 39 percent of voters believe Trump’s campaign tried to help Russia do it.But here, too, opinions were split among party lines. Belief in Russian meddling was at its highest among Clinton voters with 83 percent, while just 28 percent of Trump voters believe Russia played a role in the U.S. election, the poll found. Both the FBI and the CIA, however, agree that Russia did indeed interfere with the U.S. election, specifically to help Trump win.Perhaps most discouraging overall is that regardless of political persuasion, voters have little faith Congress will fairly and competently investigate. The poll found 55 percent of Democrat-leaning voters do not have confidence that Congress will conduct a fair investigation into the Russia allegations; Republican-leaning voters were split 46-46 on the matter.The poll, however, isn’t the first to show that Republicans and Democrats are more split than ever on the issues. A series of Pew studies over the last decade revealed that 64 percent of Democrats and 23 percent of Republicans believe humans are causing global warming — the largest gap yet. Another Pew survey found an unprecedented break between party lines on the Israel-Palestine issue. While 74 percent of Republicans sympathize more with Israelis than Palestinians, only 33 percent of Democrats do.
