Why must every election be about where our ancestors came from...it is divisive...why must every election be about religion...in America we are free to worship how we choose.....why must in every election, sex is a prime discussion when in America you are free to have sex when ever, where ever with whom ever; sex isn't a part of the Constitution.....some of the following issues are important.... "thou shalt not kill" abortion? pretty straight forward....obeying our laws/corrupt politicians and government....and we should be rectifying our extremely wastful top-heavy Federal Government whose Unions work against Americans not for them....JFK made a huge blunder there....this nation's elected should be trying to remedy (our debt) the rest is window dressing to keep you from paying attention to how close you/we are to Third World villages, town, cities etc.
Because identity politics work for the Dems and will increasingly be more effective as the demographics of this country rapidly change. By 2019 half of the children 18 and under will be minorities as defined by the USG. By 2043 half of the country will be minorities.
Government policies reinforce group identity. Certain groups receive advantages like minority business set asides, affirmative action, quotas, etc. The Dems will use identity politics more and more as they become the permanent majority party. Demography is destiny.
