This is a good point. Leftist voter groups only think for themselves. The LGBT does not what anything, that is not for them. If you could promise the LGBT community only things that will go to them, they would happy. Screw everyone else. The Democrat leadership knows this; selfish children, and will play Santa Claus and/or tell their selfish base what they want to hear.
The Republicans tend to think in terms of a bigger picture, which benefits all, such as a good economy, plenty of jobs and national defense. These things benefit everyone, including the LGBT, blacks, white and even immigrants, since we cal all use good jobs. The Republicans will not offer free sex change operations, since so few will benefit by this large expense, and there is not enough money to give everyone a big selfish gift.
President Obama, told the blacks what they wanted to hear, yet did little to alter their path. When you deal with selfish people, lying works, since they are too self absorbed to look at the big picture.
When you attempt to maximize an entire country, you cannot play Santa Claus with everyone. There is not enough resources to go around. Instead you look for solutions that work for the most people. Like the song, "you can't always get what you want, but you can get what you need."
An analogy are parents with a lot of children, at Christmas, who only a limited budget. You can't buy all the children all the fancy gifts each one has on their list. You can promise, but you cannot deliver. If you promise and cannot deliver, it will be heart breaking for all. A better approach may be to buy something that all the children can use; maybe a modest swimming pool for next summer. It may not be the sex change for Joe(sy) or the abortion for Pam, but everyone will enjoy the pool, including mom and dad; family time.
We are in this huge national deficit because of borrowing to play Santa Claus to buy the votes, of selfish people, using debt. Trump is looking to help all the children, on both sides, but in ways the selfish children may not yet see.
