Cameron - It's Too Late!

There seem to be many commentators who believe that if Cameron were to seize on Ukip policies - he could turn the wretched tory situation around.
Won't happen. If he looks FORCED to take measures - he's gonna look weak and will still lose votes. (Moreover he would inevitably water policies down to make them palatable to his own ego.)
As he hasn't taken these measures already - it clearly shows that he IS weak!
