I'm guessing that spike in the middle of last year is all the temporary government workers. I'm not good with numbers but if labor participation had remained constant, I think unemployment would be a whole lot higher than the 9.6 it is currently at.
I seem to remember from my history books that it took Reagan a while to recover from the effects of the previous administration and congress, but he still did. I'm not seeing anything like that from the current crop of "leaders" we've been subjected to.
