That's kind of a difficult thing to determine, when asked almost no one says they are, but if asked about policies, they tend to go for more progressive policies, even people that identify as conservatives will agree with more progressive policies. The people they vote for however, are definitely not progressive... Mostly, there are a few.
Then again, progressive in America is pretty much basic human rights and protecting vulnerable people which should be the minimum.
It's scary because it's falling on a lot of us. And it won't just be the US that it falls on either.
