As a former Republican Party Precinct Secretary, I beg to differ. They will take notice.
In your individual case - perhaps they might take notice, but ultimately the machine does not care. They have a greater source of money from corporate fascists and the Chamber of Crony Commerce than from individuals.
As a former precinct captain (the wife was an election Judge) - they did not care that we resigned, and I daresay applauded our departure because our “Extremism” was “Bad for the party”.
Ultimately it will not matter to the Ruling Class. They are convinced Amnesty for illegal South Americans are their future along with embracing Marxist fascism. Just look at the fruits of the leadership for all the evidence you need to understand that they no longer care about Conservatives leaving their party.
They WANT us gone. Why else would the leader in the Senate vow to ‘crush us wherever they find us’ if they did not loathe our existence as much as if not moreso than the MarxoFascist Democrats do?
