UPDATE, apparently now Welsh does most of his writing on his own ianwelsh.net, while still posting somewhat on Firedoglake
Ian Welsh @ Firedoglake blog, is a 40s-yo Canadian in Toronto with a great broad take on US economic/politics topics, with an ability to take long historical perspective, ala Thom Hartmann.
I stumbled upon 1 of Welsh's posts. Welsh is great, I'll likely become a regular reader because this guy is dropping too much insight to be slept on.
Here's an example post labeling 3 groups in US political spectrum
conservatives ("centrist" Dems like Obama)
liberals (very few exist in House & Sen)
