I didn't ask about whether you would do it to see if you wanted to join the party. Buy you knew that.
I know there are things in the Republican platform I don't fully agree with. I also know that to change anything for the better takes a long time and must be done within the party.
Its easy to make things much worse instantly, just let a party that you agree with about nothing gain power.
I would rather work within the party I agree with on 70-80% and work on getting the other 20-30 % over time.
It may take a generation to get an extra 10% that I can agree on, then again it may never happen.
