Via NBC:
Pennsylvania: Biden keeps increasing his spending to the moon, eclipsing $8 million in just one week, a number matched by the Democratic outside group Future Forward. With Trump spending just $1.4 million last week there, the total spending gap that week (when you factor in outside groups) was about $24 million to $8 million.Just how broke are they? $1.4mil without outside groups?! That's it?
Also can confirm, Biden is going insane on the airwaves here. It's hard to watch any channel without being bombarded with ads. I've seen more Trump ads recently than I was seeing before, but it's literally like 4:1 or 5:1
