Most of the students will be left leaning till 25, when they either will start earning well and shift towards either a stabilized centrist pov, or be an unemployable person who might jostle from a job to next based on their political opinions.
The opinion polls of youth being against a party or government will always be a talking points, but that's online polarization and hullabaloo.
