Not really. That's just people's perception because they don't understand bureaucracy. The reality is that life under Trudeau is not drastically different then life under Harper despite both men's opposing views on many things. This is something the Trumpites have wildly underestimated. Most, if not all the EOs Donald have signed will be eventually overturned or abandoned. These ships are far too big to change direction on a whim.
As for politicians, probably the most influential politician in the last 30 years never gained power. Nobody in politics was talking about balancing budgets until Preston Manning came along.
