I can’t predict what will happen in tomorrow’s special election in PA, but it is already a very bad sign for the GOP and Trump. GOP has had to spend millions of dollars to defend a safe GOP seat Trump won by 20 points less than 18 months ago.

Trump had to go to PA to defend this seat. The GOP is spending millions for a seat they’ve reliably held for years.

Trump won this district by 20 points last year.

Lamb, the Democrat, is up at the last poll. Democrats have been seeing 20+ point swings in their favor throughout special election season.
