Truthfully not so many people are well acquainted to he new guys. They appear to hold so much promise of a better future but then we don't possess a crystal ball that will tell us if they would make fine leaders or not should any of them be elected into office.
The older guys on other hand, despite a few incompetencies have also proven themselves to be reliable in the past, and then there's this thing that comes with "experience". I'm not here to tell anyone who to vote or who I'd be voting for. Personally if I were karma I'd pick the one the country deserves. I'll simply guard my voters card jealously and wait till the 2019 elections to put it to good use.
