Eminently reasonable at this point in time. I’d consider making AZ a Tossup, though
The reason I'm not doing so yet is because the polls that were released so far weren't the most reliable, being either Gravis or Garcia internals, though I will say that this race is probably closer to tossup than likely.
OK, IA, GA, TN, AK all have the potential to become tossups over the next months.
OK & IA - They definitely could, but I think we need some polling first before I'd even consider making that call.
GA - Probably the closest out of all of those you listed to becoming a tossup. It's much more reasonable now than ever to see Governor Abrams.
TN - As far as I know, there hasn't been much evidence of a competitive race, but I may be wrong, especially if the primary becomes as messy as in Georgia.
AK - I agree with you there, too. I guess putting it as "Lean R" is me "playing it safe" due to the division, but I feel like it won't be like Florida's 2010 Senate election like many think. I could see the winner only beating the second-place candidate by less than 10%.
