On the contrary, Rajoy is going to come out reinforced from this. The rest of the Spaniards, many of them from the Catalonia region, have been waiting for a long time a strong response to the secessionist thread of the local government of the Catalonian region. Now finally Rajoy does a strong response (although not strong enough for many Spaniards and the army should have been deployed also and it has not been). So most Spaniards see now Rajoy as a strong leader that can avoid an illegal secession of one region of Spain. This will give him an absolute majority in the next elections.
