Never. Strategically it’s a bad move. It takes a long time, the populace doesn’t like the attempt to “reverse the election”, and if they succeeded it would give Biden a chance to separate himself from the Obama legacy and actually give him a small chance of winning the election in 2016.
Problem is I see a worsening ‘progression’ in Obama’s crimes – lawbreakers are only emboldened by getting away with their criminality.
It will only get worse from here on out, at some point the GOP will have to take action.
BTW, the man should have been impeached yesterday, but that’s just me.
