I don't have a particular problem with it, as long as they are candidates that will work hard for their constituents.
It will not matter one jot though, if, as is probably going to be the case, the constituents would vote for the proverbial monkey wearing a rosette of the colour you are brain washed in to voting for. 
Let's face it, all parties are happy to use nepotism.
What I do find annoying is partisan politics where one party accuses the other of nepotism, class and educational privilege, being millionaires and posh etc. and stupidly opens themselves up to be, quite rightly, called hypocrites. They make themselves look stupid and the ease with which it is carried out is often quite shameful.
I do as a matter of fact think the voter might just struggle with being so blatantly used if they have never seen hide nor hair of them in action and all they have to go on is the reputation of the parent. Blair, Straw, Kinnock and Prescott, they certainly are names to have made a lasting impression aren't they.
