This is exactly why it will be difficult. Not a lot of nationally prominent Democrats are from or have spent a lot of time in deep red areas where antipathy towards them would override fairness and wisdom (like the NY jury). The key ones are all from blue states where they are untouchable (Pelosi, Schumer, Biden, Obama, Harris, Whitmer, Sandy the bartender, Newsom, Shapiro, etc.)
A democrat need not live in a Red area to be indicted there.
They need only have committed a crime within that jurisdiction. Flight connections at airports would be a solid place to find crimes committed during a layover.
That’s why you use conspiracy statutes. A conspiracy can be tried in any place where an “overt act” of the conspiracy took place. So if a bunch of leftist meet up on a bus in a red county, and then they drive into Nashville, file conspiracy charges where they got on the bus. If two individuals conspire to falsely charge Trump, a Florida resident, than RICO charges could be filed in Florida by the AG. Also, red state Democrats should be prime targets. We need creativity to make this stop, IMHO.
