Remember ... it was the republicans who started the 'make Obama a one term president' stragedy and the rest of the right lined right up behind it. The democrats could/would employ the same tactic or worst, push gun control riders onto republican sponsored bills.
SHTF scenario is the republicans win control of the senate and Obama gets re-elected.
Excuses are tools of the incompetent used to build monuments of nothingness. Those who use them seldom amount to anything.
