I haven't read all the comments on this thread but have skimmed through a few.
I like Nicolas Sturgeon, many of the points raised here (power mad, micron a aging, centre if attention) are actually just her being a leader, the buck stops with her. Giving the speeches and updates herself lessens the mixed messages that can arise when many people take the podium.
She has a plan and follows it through, they may not be popular but she is doing what is best for the country with the limited powers she has - she cannot close international borders, she cannot borrow large sums of money, Westminster has to borrow on Scotland's behalf, all the furlogh money and business grants are still paid for by Scotland, we just don't get a say in how much we can borrow or the terms of the loan.
Drug deaths - drugs are a reserved matter, Nicola Sturgeon cannot roll out the plans she wants as Westminster control the Drugs Act and welfare budget, so the SNP are expected to solve the drug problem but are being denied the tools needed to do it.
As for independence of course that is her goal, why wouldn't it be? Yes I believe independence is the way forward, we cannot continue as we are.
Independence does not mean Nicola Sturgeon and SNP being in charge, in fact SNP will no longer need to exist if independence goes ahead, at which point any party could be voted in, a right wing government, left wing or mixture. SNP are a means to an end that's all.
