It's one thing when Obama is preaching to the choir and making a meaningless comment out of fun. It's another thing when someone takes that meaningless comment and tries to put actual meaning behind it. Democrats are quick to latch on to superficial emotional surfaces of issues, like this. Republicans peal away the layer to get at the real, substantiate issues.
What you haven't been told is that the Bush years weren't that bad, especially since how 9/11 and the grounding of airlines hurt the economy. Unemployment was 5.1%. This being said, why do you assume that Conservatives WANT to go back the the policies of Bush? Obama wants to imply they do. It was Bush's spending that gave birth to the Tea Parties, before they were Tea Parties. Some Conservatives were disillusioned with his spending early on, even before 9/11, myself included. He tended to believe what he wanted to believe about things, which resulted in "don't rock the boat" politics with the impending mortgage meltdown.
This being said, Democrats are oblivious to their contribution to the mortgage meltdown. They strong-armed banks into issuing more sub-prime mortgages than they wanted. ACORN did this on the local level. The pushed Fannie and Freddie into buying up these sub-prime mortgages and issuing mortgage-backed securities. Wall St. greed bought these up. Dems did this to look like heroes (at any cost) to their constituents looking for low-cost home ownership. Fannie and Freddie, the biggest facilitators to the recession, are except from the latest financial overhaul. Dems are, once again, pushing for mortgage packages with $1,000 down payments. They don't get it!
Obama and the Dems are using yet another superficial, emotional statement about going back to Bush policies. You would have thought that they would have learned after "change" and "hope". They're pushing these because what they have done is just not popular. Their "triumph" of health care is showing it be a bloated, bureaucratic mess that keep getting more expensive and it's barely even started. It was crammed down the throats of American, along with gross bribery.
Listen for more superficial, emotional complains about Republicans to come. None which will be able to stand up under scrutiny for those who choose to do so.
