After a month of continuous setbacks, most of them self-inflicted, Sunday brought another unwelcome development for Republican presidential candidate Donald Trump -- this time in the form of poll numbers.
Two new polls released on Sunday both show Trump on the decline from one month ago and trailing Hillary Clinton, the presumptive Democratic presidential nominee, by a significant margin.
An ABC/Washington Post poll finds Trump trailing Clinton by a remarkable 12 points. In that poll, 51 percent of voters said they would vote for Clinton while 39 percent said they would vote for Trump.
The poll shows an astonishing 14-point swing from one month ago -- Trump has fallen by 7 points while Clinton has gained by the same amount. Last month, Trump had a slight edge on Clinton in the ABC/Post poll, with 46 percent to her 44 percent of the vote.
An NBC/Wall Street Journal poll also released Sunday finds Trump trailing Clinton by 5 points. Clinton carries 46 percent of support in this poll, while the real estate mogul takes 41 percent.
The NBC/WSJ poll shows just a 2-point decline for Trump from one month ago. Clinton's support has remained the same from one month ago, based on last month's NBC/WSJ poll.
According to the HuffPollster average, which aggregates all publicly available polls, Clinton now leads Trump with 46 percent of the vote to his 39 percent.
Trump also trails Clinton in four key battleground states, although by smaller margins, according to a set of CBS News/YouGov polls released Sunday.
Still, it's important to remember that with about five months left until the general election, the outcome is far from certain. Polls become increasingly more reliable in the final 100 days before a general election. As of Sunday, we're still 134 days out.
Trump was looking competitive in early May, with some polls even showing him ahead of Clinton, but many observers suspected this was because Clinton was still occupied with the Democratic primary and had not yet shifted gears to the general election. Her support has increased since she became the presumptive nominee and since fans of Sen. Bernie Sanders (I-Vt.) have started to shift their support to her.
Trump, on the other hand, has faced criticism and blowback for several remarks he's made in the past month. In early May, he accused a judge who is overseeing the Trump University fraud case of being biased because of the judge's Mexican heritage. A majority of Americans felt these comments were wrong and racist.
Things only worsened for Trump when the Federal Election Commission released the May finance report for his campaign, revealing that the real estate mogul was financially in a hole.
Most recently, Trump has received further pushback from the media after calling the Brexit vote, which caused the U.S. stock market and the British pound to plummet and which has been widely interpreted as a symptom of racism and xenophobia, "a good thing." (Those comments can't have affected the polls released Sunday, since Trump made them after those polls were conducted.)
Trump's campaign manager, Paul Manafort, insisted on Sunday that the campaign is doing just fine despite recent setbacks.
The ABC/Washington Post poll surveyed 836 registered voters using live telephone calls from June 20 to June 23.
The NBC/WSJ poll surveyed 1,000 registered voters using live phone calls from June 19 to June 23.
