the OP is dumb for various reasons, but two are:
the presidential election was not a one issue election
the house pubs creamed the dems in 2010, and gained seats in the senate shortly after obamacare
2008, 2010...okay...and the last election where Romney and Conservative America ran agaonst OBAMACARE, and where Obama himself embraced the term 'Obamacare'?
Get over it.
The people voted based on the lies that obama told about it. The vote would be quite different on obamacare today.
