The Democrats lost 67 seats.
The Progressives lost 3 out of 83. That accounts for 4.4% of Democratic losses, for a caucus that represented 32% of the total Democratic party.
The Blue Dogs lost 28 out of 54 (more than half of their members). That accounts for 41.7%, almost half, of Democratic losses, out of a caucus that only represented about 21% of the party. The Blue Dogs really punched way above their weight in this election.
Your sarcasm detector is on the fritz.
