These are all things he's tried over the last couple of weeks to try and win back a very jaded GOP electorate: he's promised a $5,000 check for every American if the GOP wins, he's tried a deal with Russia to get diesel and ease prices, he just yesterday (?) said he'd pursue a reduction (not an end) of aid to Israel, and he has of course been having tons of rallies.
It's not going well. Florida is in play for the Democrats.
