Biden needs to continue to push hard here, especially for NC.
Can't speak for NC but I'm starting to see a lot more Biden ads over the last few days in Georgia.
In the Chatt media market here: have been seeing Ossoff TV ads for over a month, but have yet to see a Biden ad (and certainly nothing from Warnock or Lieberman; granted I do not watch much television, so maybe they're there
now but I've yet to spot one despite seeing plenty of Ossoff primetime pitches).
This isn't particularly unusual given that ~70% of the Chatt media market isn't in GA, but generally "serious" Democratic candidates bite the bullet & do advertise here at least at some point (Carter, Nunn, Abrams all ran ads here - along with Evans in the '18 primary given this was her ancestral home).
Media market-wise, GA simultaneously has an advantage and disadvantage. On one hand, a majority of the state is in one media market. On the other hand, pretty much everybody else is in a media market that significantly overlaps with other states (Columbus, Augusta, Savannah, Albany, Chattanooga all have significant minorities or majorities of their markets out-of-state). Macon is the only other real media market that's wholly contained in-state. Nevertheless, well-funded and credible candidates do generally spend across all of these markets, while the less serious ones focus on Atlanta with a sprinkle of ads in Macon. If Biden is
seriously contesting GA, then there should be ads running consistently in all 7 of those MMs I mentioned.
In the end and as far as "Generic State" goes, I think the advantage/disadvantage balances out (i.e. there are plenty of states with multiple mid-sized media markets contained in-state (NC), states with multiple larger markets but a few split-state ones (OH), states with tons of media markets in general (TX), etc) so credible Democratic statewide candidates
should be spending in all of them relative to what candidates in many other competitive states have to spend/do.
