You will likely find that most people don't want to stand with someone who votes the wrong color. You'll likely also find it isn't all that different than 1, 2 and 3 generations ago with the exception that more and more people are devolving to the stupid side of the aisle at the same time that more and more generational dolers and imported voters are selling their vote for giveaways.
Perhaps that's true of the people you know, but none of the people I consider friends would giveadam about who one votes for. We can disagree without thinking [even in private] that the other is on "the stupid side of the aisle", because there's stupid on both sides.
Those who buy the myth of 'generational dolers' and 'imported voters' are stuck in a mindset from generations ago, encouraged to stay there by leadership that has profited immensely from the politics of fear and loathing.
Anyone who always votes for the same party, regardless of the issues or candidates, is brainwashed. Or brain dead.
PS Agree with Turtle about the people in the South being friendlier, it's why I've always preferred to live there. That, and it's near impossible to find good sweet tea in the North!
