I do not worry about polls this time of the year. In 2016 not a single poll this time for the year got Trump winning anything. - it narrowed a bit - nearer \to the election date when two out of all pole indicated that Trump might win the election, The polls misread the situation totally - in the last pole before the election Clinton was leading Trump in Ohio by ten points - days later in the election Trump beat Clinton by 11 points.
The latest scandal about Flynn is just he start of it - there are going to be more coming, It is clear that a string of FBI, CIA and Obama White House officials are going to be arrested before the election. Hunter Biden is also on very thin ice as well. Papa Joe's role is going to be scrutinized and he will be extremely lucky not to be in the dwang too, Then there is also that $1,5 billion from China that will have to be explained away by the Democrats,
The Democrat supporting press will try and hide things away, but I don't think it is going to work.
