Democrats were celebrating being up 10 about 2 months ago. Now they are down to the GOP for the first time in a while.
Trump has 47% approval

Memos, Russia, wife beating staffers, porn star payments. None of that matters in terms of election prospects. Normal people aren't following the news like that to care

Tax cuts were a shot of adrenaline to Republicans and Trump. They are selling them hard and folks are receptive.
If Democrats don't get their own spin on the cuts to take hold quick, they are in big trouble

Drop the memos stuff. Don't take the bait on Trump's lawyer's porn star payment. Be laser focused on the consequences of the tax cuts and only that.
