I've seen the argument in here that "biden's approvals aren't a proxy" for midterm margins.
I don't disagree. Nobody is arguing that if he is at -12 on election day, that will translate to GOP+12.
Rarely does that ever happen in US politics.
But at low approvals, what does happen is that you begin to bleed enough support to the point where a +0 midterm starting point becomes -1, then -2, then -3, etc as your ratings drop.
If even 5-10% of biden voters who now disapprove of him switch to the gop for 2022 and/or stay home, that is enough to swing the midterm elections. That's what we saw in 2018 and 2014 and 2010.
tl/dr: nobody is arguing that approvals exactly match margins, but they do generally determine how midterm ends up.
Stop comparing Biden Approvals to Midterms of 2010/2014 lol you keep doing that Trump netted 2 S Seats in 2018 and netted H seats at 44% approvals don't you see the State by state polls that have Kelly, Hobbs, CCM and Hassan and Golden 50/45 the GCB is tied or D's plus 2 winning and Golden we haven't seen any WI polls but Fetterman is the fav, it was 88M votes in 2010 it's not a 413 map it's a 303 map and it's 110/125 M votes we lost WI, MI and PA in 2010 because it was 10% unemployment it's 4% unemployment and Trump netted S seats in 2018 due to 4% unemployment too and Trump netted H seats in 2020 because unemployment was trending downward from 9/7%
Trump lost 33 H seats in 2018 due to impeachment on Ukraine
Users don't read polls they just use Biden low Approvals as a proxy and Trump did quite well in red states at 44% Approval
Whitmer is almost certain to win Craig isn't on the ballot and Shapiro and Fetterman are gonna win, that takes us to WI, they haven't given us any polls but Johnson is at 37% Favs not 60% like Oz
