This is a follow-up to my earlier post today.
The Washington Post has been fact-checking Trump's speeches since the beginning. The latest one they looked at was his Montana rally on July 5.
In this talk Trump made 98 statements of fact. The Post found that 45 statements were false or mostly false, 25 were misleading, 24 were accurate or mostly accurate, and four were unsupported. That's about three of every four statements. Two of his more egregious claims were - he draws bigger crowds than Elton John and he was the first Republican to win Wisconsin since 1952.
Then, he has the other problem of changing his 'mind' almost every day. Witness his statements re NATO and Prime Minster May.
