I read that more as a "statist (which both republicans and democrats are) vs non-statist (libertarians, anarchists, etc)" shading. The parent mentioned both Bush and Obama, so he's clearly suggesting that BOTH democrats and republicans like bigger government. Both parties have little pet "get the government out" issues but nothing serious.
> You think that Bush's and Obama's massive expansions of government weren't all about amassing and maintaining political power? Those guys both believe that more government power/money solves all woes.
This is clearly bipartisan. He's attacking both democrats and republicans and suggesting that on many issues there's little difference. I don't believe it's possible to argue that it's partisan. It attacks both sides.
It might be tribal, but on an axis orthogonal to the traditional left/right political spectrum.
