In addition, it can be wasted, typically by failed attempts to promote unpopular policies that are not central to a politician's agenda.
And thanks to the RW media propaganda it was NOT popular around the mid-terms:

Many Republicans ran on a promise to repeal the law, and beat incumbent Democratic opponents who had voted in favor of the Patient Protection and Affordable Care Act.
The poll numbers and the losses we experienced during the mid-term election show this happened.
