Is Theresa May trying to not win the election with a large majority?

Theresa May's tactics during this general election seem odd. Alienating pensioners seems to be an especially odd tactic as they are more likely to vote than other age groups, and more likely to vote Conservative.

So the various policies in the Conservative Party manifesto that are detrimental to many seems odd. Unless that is if Theresa May really is a Remainer and wants to be re-elected Prime Minister with a reduced majority or even at the head of a weak coalition government. That way Brexit could be derailed.

It's not beyond the realms of possibility and might also explain her bullish comments on Brexit. Is she trying to push Remoaners away from voting for the Conservative party?
