The league has just gotten to the most interesting stage and for sure we can point to the dominating team for this season just as you have said Rangers and Celtics are topping the table and for sure Rangers seem to have more chances of winning this season despite occupying the second position currently, the reason is that the last two games happen to be their worst games this season and the reason why there still at the second position and looking at Celtic few next matches you will notice that are up against clubs that can drop them from the top of the table if care is not taken.
I don't get the logic behind you rooting for Rangers to win the Scottish premiership this season even after being 16 points clear behind the league leaders Celtic who have put of their better performance gotten that far in the league with 29 matches already played and just 9 more to end the season.

If you assume Celtic might drop points then what makes you think Rangers wouldn't as well drop points against some of their opponents in the 9 games left to rap up the season. It's obvious Celtic has conquered this season and rangers should strive on maintaining their second position that Hibernian or Aberdeen not dispose them before end of season.
You may have gotten my analysis wrong and assumed that I stated that Rangers are going to overturn the leading club Celtic, this is not the case in my statement and I am sure that it going to be almost impossible for Rangers to be able to accumulate such 16 point advantage on Celtics side and even the current performance of both clubs is not in equal basis, but still, at that we can't out write the possibility of having advantage from other clubs that are lower on the table and in the Turkish league that could help Rangers indirectly and helping to pull Celtics down in points and ultimately putting Rangers on advantage, that just speculation so I don't take it to means fact since only time can tell at the moment.
