ya 4 years of cockblocking is enough to drastically change the recession, bush took a prosperous nation into decline in roughly 9 years, give or take based on the full impact.
besides all that, do you not realize romney is pure shit? he is a lying conman that will rape the US and leave it bare.
Obama had a supermajority in the Senate and a huge majority in the House. Or did you forget that (that's how we ended up with ObamaCare).
Besides, the party out of power always plays obstructionist, or did you also forget about all the "cockblocking" the Dems did during the Bush years?
