How come it wasn't a problem when Republicans overhwhelming and unabashedly supported everything the Bush administration did, even when it put the country at deep risk? How come this wasn't a question, then?
It was a problem. Democrats took over in 2006 due to the reckless behavior of the Republicans. Everything was going fairly well until the Iraq war. Once it became obvious that Sadam was bluffing about WMDs, the war became an issue that divided the country. It was because of that (and spending) that people went back to the Democrats. Same thing happened again in 2008. They also elected Obama, under the misguided notion (I admit that I was duped too) that he was a centrist and would put an end to corrpution and "the poltics of the past." Instead, he took what Bush was doing and ran with it. In the case of spending, he not only ran with it, he doubled the speed! He supported/pushed bills and ideas that were not popular with most Americans (like the healthcare bill and sucking up to our enemies). As a result, most people voted Republican this time. Not because they had faith in the Republicans again, but because it was their only other choice. They were voting against Obama, not for Republicans. Now we (conservatives) just need to make sure that they follow through on their promises.
