Although Iowa isn't deep red like its neighbor to the west, Nebraska, the state has been a frequent source of frustration to Democrats. President Barack Obama won Iowa in both 2008 and 2012, but the state went to Donald Trump in 2016 and 2020. And Iowa is home to Religious Right-friendly Republicans...
It’s roughly half of Republicans who responded to the polls right now, so roughly a quarter of Americans max.
Still, it’s worrying. I don’t know how many Republicans would vote for Trump if he wins the primary. I thinks it’s about half of them for that too, so he’s unlikely to win the general, but who knows at this point?
