well that's what happenning in countries where there are no term, like my country for example, it's been almost 20 years, and AL is still in power, add some sprinkle of 'One Party Democracy' and some whiff of 'Prime Minster in Power', and you got something that's not much diff from autocracy
Yes, cuz those countries have shitty electoral processes. If the democratic and voting rights of the country is strong, then there is literally nothing immoral with there being no term limits. In a way, adding term limits, is anti-democratic, cuz there can be one guy people really like and has proven themselves capable, yet "the rules" say they can't run again.
