Its not the numbers that are lying... I'm not one to stand up for polls as i think they are way over used and over emphasized during campaigns. But the polls said that more people favored Clinton and 3 million more people voted for her. I believe all scientific polls were correct within the margin of error except for one or two states.
As for Trumps credibility... That is so far lost in the mud and just sinks deeper and deeper with each lie he tells. If you really think it hasn't taken a hit over the past few months then you are living in a fantasyland my friend.
1. Hillary DID NOT win by 3 million votes. She lost the popular vote by millions, and this will be proven in the 2020 election, after millions of illegal alien voters are deported from the country, if proper steps are taken to prevent them from re-entering or voting from outside the US. I would guess this will happen.
2. As for the polls, they were a laughingstock, and you are showing yourself to be quite naive ( a common trait among liberals nowadays)
3. Trump's credibility is only being questioned by a minority of Americans, who voted for Hillary, who ran the most DIShonest campaign in US history. Look at all her lying TV ads.
