Polarization if a Great Depression 2 happened under a Kerry Administration?

[Huey Long is a Republican]

We all know the story of the Great Recession and how it basically allowed Obama a skyrocket victory and then under President Obama, we saw polarization before skyrocketing under Trump and now Biden.

In 2004, though, there was a genuine chance for John Kerry to become President if Ohio had gone to him. People may say that a Democrat would govern differently but I'm quite unsure about that. Reason being that in the oughts, the Democrats and Republicans had similar platforms and were mostly just moderates instead of being Liberal/Conservative full bore on most issues.

So, if John Kerry had won in 2004 and a Great Depression 2 happened under him, how do you think political polarization would get? Do you think it would still be as bad as OTL or do you think it'd cool down quite a bit and go back to 50/50 after a period of dominance by the party that takes power in 2008 or do you think Polarization would hit a high relatively quickly?
