I think he/she would look something like this:
Social Issues:
-Pro-life with the exceptions of rape, incest, or health of mother Pro-choice until around 12 weeks, then those exceptions
-Pro-SSM
-Pro-marijuana decriminalization
-Pro-background checks, but anti-assault rifle ban and pro-2nd amendment. Also supports high capacity magazine ban
-Believes that climate-change is real but completely ignores the issue while campaigning (since campaigning on combating climate-change might make one appear like a smug elitist). and talks about the future we're leaving our grandkids and good-paying clean energy jobs. Campaigns on being pro-science and facts.
-"Let's get our asses to Mars before the Russians"
-Pro-death penalty Doesn't have a strong objection to the death penalty
- Centrist on immigration. Doesn't believe in open-borders, while not being a Trump-style extremist on the issue either.
- Pro-temporary Syrian-refugee ban extreme vetting*, but strongly against Trump's Muslim ban.
- Downplays on social issues while campaigning and focuses mostly on economic issues.
Economic Issues:
-Strongly pro-minimum wage increases.
-Strongly against making any cuts to entitlements like Social Security.
-Supports expanding Social Security and Medicare.
-Pro-Wall Street regulations
-Supports raising taxes on the rich and cutting taxes for those who aren't.
-Anti-free trade
-Anti-Obamacare, while supporting a plan to replace it. medicare-for-all. Doesn't frame it as a government takeover of healthcare, spins it as Medicaid expansion.
-Pro-infrastructure spending
Basically as economically liberal as possible with the exceptions of supporting tax cuts for those who aren't wealthy. Being economically conservative is absolutely toxic. The only conservative economic position that is even remotely popular are tax cuts.
Foreign Policy
"Realist" Non-interventionist, "bring the troops home"
Other:
-A white male (stfu we almost elected an old probably atheistic Jew with bad posture, people don't care about that BS) who grew up in rural America.
I think this would be the most electable candidate ever.
*we already have extreme vetting but that's what people want to hear
This actually looks pretty good, assuming the candidate is a Democrat. I don't think a candidate with the OP's stated positions could win a Democratic primary, which is half the battle.
Well, obviously too left-wing for the establishment.
