Fur Shur there aren't nearly enough ~ should be half the teachers in the country standing their on their thumbs or something but they're not.
But, let's go back to your belief that only unemployed, Catholic union members voted for Obama.
Think about that a second ~ why were Catholic union members "unemployed"? Do unemployed people pay union dues religiously?
What you're doing is you are working in broad categories that you think are relevant to the question of who wins elections.
Fact is in a society organized such that it's political dimensions follow a mathematical shape known as a Bimodal Saddle, you just don't get nice, neat, micro categorization.
What you get are two core groups ~ one we call Republican and the other we call Democrat. There's a thin fringe around each.
The objective in any election is to PULL IN your own base or core voters, AND attract one of the factions that make up the other party to vote for you.
The two poles are, at this time in history, organized differently. The Democrats are composed of a number of special interest groups. The Republicans are composed of a number of occupational categories as well as religious traditionalists.
Neither pole pulls in everyone. You have half the union guys voting for Republicans and half for Democrats, yet their union affiliate is always part of the Democrat Party governing council!
The objective for the Republicans in any election is to try to pull off a few more union votes from the Democrat column while NOT alienating the far larger numbers of union members who almost always give Republicans their votes.
The objective for the Democrats is to pull in their own "we can count on these guys" union member votes (half the total) while also pulling in a few more union members who usually vote for Republicans ~ but the Democrats don't do that without risk. They've already alienated half the union members with their BS and betrayals so they don't want to alienate more of them.
Consequently you don't see Republicans running around saying union members are scum, nor do you see Democrats running around saying that union members who vote for Republicans are betraying their class, or are scabs.
Just doesn't happen ~ yet, I gather from the way you want to categorize folks, you think you can get more votes from the other side's factions by calling them names and belittling them.
That doesn't win elections.
I'd go into this in a bit more depth but it's getting late. Fur Shur the Republican Establishment's wealthier blue-hairs imagine that we win votes by beating up on voters, but fortunately they only control the RNC. That's balanced by the true-believing Leftwingtards in the Democrat party. They think they get more votes by conducting a burn-all-bridges class warfare.
LOL
Your immature summary fails to invoke common sense, or experience.
I don't pander for votes, patronize, nor do I try to be an amateur psychologist. Indoctinated masses, who fail to use common sense, fall into the pandering/patronizing mode to try to fool people into voting their way. I call a spade a spade, myself, and am not into "political correctness" and afraid to speak the facts.
If that's losing votes, then the votes you're seeking are people who can't think for themselves, function on their own, and love the Nanny State.
Singing Kumbaya, holding hands, and chanting do NOT make a strong Nation. Without principle and values, we wind up with what we have today, which is parasitic/dependency on others, but the "others" are nearly used-up, and running out of benevolence.
