This election is going result in so many new politicians. Quite a few Republicans and Democrats are not running this time out. I wonder if this is a record.
I will need to read rollcall and thehill to compare this year to past reapportionment years, but here is a list so far. Plus there are the head to head contests in primary or in November which freepers can read on these sites.
