You can't compare Scott Brown winning in 2009 with this, because he won on actual voter discontent along with the poor campaign that Coakley ran. If Jones manages to win this (which looks likely), it will be because his opponent was a sexual predator who lusted for teen girls - not because Alabama is sending a message about policy or Trump, pretty much the exact opposite of Brown's 2009 win.
You can still compare them. Unless the items are comparison are literally identical then you can always criticize the comparison by saying it's not the same thing, as you are here.
So maybe you think it's a bad comparison maybe, but you can still compare them.
