Maybe but she could just as well just want those watching the show to believe it, concerned with what would happen if they dont. Voters might stop believing in Obama and socialism.
Republicans had/have similar problems. GWB cut taxes early on 2001/2003 but toward the end of his presidency 2007/2008 the economy unravelled. That allowed Dems to claim (falsely) that it was at least partially the tax cuts that caused it. .
Because Bush left office with a mess, Republicans are put in difficult situation claiming the Bush economy was great (he gets the credit) and bad (Dems get the blame) all at the same time.
It's called politics.
The smart play would have been to abandon and blast Bush.
