Florida senate race, new poll from Florida Atlantic University:
Scott (R) : 44%
Nelson (D, incumbent) : 40%
Not to pay much attention to it because of a lot of problems. To name three, from a sample of 1,000, 190 didn't vote in 2016. The quotas for Democrats and Republicans are equal, set in 340 and almost equally distributed by gender. The presidential vote in 2016 is strongly skewed towards Trump.
By any reasonable adjustment to its results, the election continues to be a toss-up.
Which is why talk of a blue wave is, at best, rather optimistic IMO.
I think that unless something remarkable happens between now and the election, the Democratic Party will do well to retain 48 senators and make small gains in the house but not enough to get anywhere near a majority there.
"Something remarkable" would be something like an outstandingly popular new set of policies, or a picture of President Trump in manacles being led of to jail.
