Do you not think the timing of these smears is revealling - the day of the 2nd debate. Murdoch and the rest of press have picked the party to support (most Tory) so they don't want to look foolish when that party loses.
If the Tory plan is to try to prove the LibDems are the same as the rest of them, then they will come unstuck in tonights debate, because non of the other main parties wants to scrap Trident.
Clegg will be more defensive tonight and the Tories will be on full attack. But Cameron is light on proper policies. Remember last week's statement about needing Trident to bomb China, I expect that gaffe to come back and haunt him tonight.
But the most pressure is on Cameron. His TV friendly touch eluded him last week, and for the past 5 years they have be telling us they have changed and they are the nice Party. If he is nasty to that nice Mr Clegg, he could well come second and third again, and the Party will be over for thew Conservatives.,
