Conservatives are easier to divide given their reliance and belief in independence. Liberals are better at sticking together in the name of a common cause even if it means sacrificing/being flexible on some of their individual beliefs.
Conservatives by nature tend to be more stoic and stubborn in what they believe. My experience/observation of it anyways.
It's why Liberals appear to be easier to 'brainwash' and buy into a hive minded mentality. You tend to have younger people with little life experience and immigrants who don't identify with the culture/identity of the place they're in buying into this thought process Vs the stubborn set in their ways Conservative who wants things to remain the same because 'that's the way it's always been'.
Conservatives will always feel like they have something to lose with change while the liberal will feel that change is needed because they don't have anything (or enough) of something to begin with.
