Theoretically, there are multiple dimensions where one can be more conservative or progressive – economics, social issue, foreign policy, nationalism.
In Israel, you have multiple parties that select different positions along these dimensions. For example, a religious party can be left-wing on economics (asking for support), foreign policy (“pro peace”), etc.
In US, with 2 parties, there is a salad of different position that differ over time. Trump, for example, took over some populist positions from Dems.
Personally, I am registered as I, and when asked who I vote for, I have to answer – I consider each election on merits, but never yet ended up voting for a D… I also see (mostly D) votes by specific recent developments, but I don’t think any of them ever voted for R before that.
some of the D- positions are beyond my red lines: previously, sympathy to Soviets, and recently hate of Israel. “I don’t need my friends be public about it” is great – unless you actually need [ublic support.
Also, despite R Avigdor Miller position, many observant communities want democratic economic policies – increase in welfare and other redistributions.
