I suppose, although a lot of people just go along with the crowd, jump on the bandwagon, or whatever side they think is winning.
Remember the ferryman from The Outlaw Josey Wales? He would either sing "Dixie" or "The Battle Hymn of the Republic" depending on the allegiance of whoever was approaching. Taking the wrong political stance could not only hurt his business, it could endanger his life.
So, a lot of people are simply wishy-washy fence-sitters. Kind of a pity, actually, as it tends to have a deleterious effect on democratic systems.
The same is true about many issues.
Like people's position on abortion and attending church. And their attitude to education and even creationism.
People tend to pick up the social opinion around them.
Socially both parties are close to identical, so the trend is heavily reinforced.
This has Become less the case in the old world in recent years. But it is still very visible in the USA which seems far more social conformist.
