There are two tactics at play here and neither is very bright. IF, and I say IF an opposition candidate has real baggage, you hold on to it and see how far he gets, then drop the bomb.
Here they are attacking out of the gate, on petty insignificant issues on all candidates, apparently to undermine faith in all the Republican party. A very, very stupid tactic when you are trailing.
They have always been sore losers and now, after last November and Obama's growing list of severe weaknesses, thousands of lies, fabrications and utterances being continuously exposed, they are in panic mode. They have no viable candidate and those sniffing at the possibility are simply not presidential timber.
About a year after Obama was elected and these boards were filled with leftist arrogance, I advised the chickens would come home to roost. Payback is just beginning, the Senate is not done investigating the IRS scandal, I suspect the majority, having been beaten and trashed by Harry "smash mouth" Reid are going to be less than cordial about ramming stakes into the Obama administration and the Democratic party itself and the dregs who occupy chairs in congress.
The Democrats in their strutting arrogance forgot the first rule of politics...."they" can shoot back.
Now, with no prospects, no forwards, no game plan, they see the opposing team, bigger, stronger, smarter skating at them in a 5 on 3 rush and all they can do is yell insults at them.
