How can an Elected Official in a Democracy, 'shut down' the Government he was 'elected' to Govern?

How can an Official elected in a Democracy, shut down the Government he was elected to Govern? Does that make sense? A Democratic Nation and its Government is a Political 'Institution' that exists by virtue of its 'Constitution' and not by virtue of some High 'Political Office'. No Person elected to High Political Office has the Power to shut down the very Government he or she is supposed to be 'Governing'; particularly in a Democracy. Certainly, an 'Autocrat' can 'shut down' his Government, if he chooses, but that never happens because Autocracies 'nourish' the 'Ego' of the Autocrat. 'Office Holders', in a Democracy, are 'elected' by the 'People' at the 'Bottom of Government', to Govern, not to shut down the Government. In a Democracy, no one can shut down a Government that 'exists' by virtue of a 'Written Constitution' that is still in existence. The 'Constitution constitutes us'. All Politicians, in a Democracy, know or should know, that a 'Shut-Down' of Government cannot be used as a 'threat' to force an 'adverse' Political Party to accept some 'adverse' Political Ideology. That is not a 'Political Act', that's destructive. The Government at the Top is unraveling. Shutting down Government cannot be used to acquire some 'Economic advantage'. A 'Revolution' that 'could' be occurring at the Bottom, is occurring at the Top. That's unheard of. How sad, there's an Official at the very 'Top' that is not a 'Real Politician' and does not know what he's doing. Of course, the 'Bottom' is also 'effected' because the 'Form of Government' is 'Democratic' and the 'Will of the People' is really at the 'Bottom', not the 'Top'. The Top 'serves' the 'Bottom', and even allowing for different 'Ideological', or Party Differences', that does 'not mean' He can 'shut down' Government. We need a 'Real Politician' at the 'Top', not an 'Economist', nor a 'Billionaire', nor a CEO, that does not know what he's doing. A 'Real Politician' is 'motored' by the 'Equality and Freedom' of 'each' and 'every' 'Real Individual' at the 'Bottom' of Government. Where are the Real Politicians?
