Could someone please come up with an online tax calculator that includes all of each of John McCain's and Barack Obama's tax proposals? I wrote a few weeks ago about how alchemytoday.com came up with a tax calculator using data from the non-partisan Tax Policy Center. Yesterday the Obama campaign came out with a tax calculator on its own website showing how much your own taxes will be under his plan.

I got a flurry of comments on the old post saying how Obama's tax calculator wasn't non-partisan. Um, yeah, I realize that. That's why I sent readers to this non-partisan tax calculator.

I still think we need a more comprehensive, non-partisan tax calculator that takes into account the various sources of income and deductions. (Though, the more complex a calculator is, the more it's like really doing your taxes and so unappealing.)
