Perhaps its because liberalism represents intellectual ideas? Perhaps something can be said why political scientists tend to be liberal.
Intellectualism means reasoning and thinking rather than emotions.
Liberals use emotions and feelings. Liberals do not think or have common sense.
If you did you would not continue to vote for Dems.
Dems always promise equality, prosperity and security. It never ever happens.
All it does is bring misery, poverty and always ends up 100% of the time in tyranny.
I think that the Author and Historian Paul Johnson said it the best;
"It is not the formulation of ideas, however misguided, but the desire to impose them on others that is the deadly sin of the intellectual. That is why they so incline by temperament to the left. For capitalism merely occurs, if no one does anything to stop it. It is socialism that has to be constructed, and as a rule, forcibly imposed, thus providing a far bigger role for intellectuals in its genesis. The progressive intellectual habitually entertains Walter Mitty visions of exercising power".
Every single bill that Dems pass has been forced upon Americans.
We are forced to pay for Social Security, forced to pay for Medicare & Medicaid.
The New Health Care Bill was not liked by a majority of Americans, but because they had the numbers in the House and the Senate it was forced upon us.
