Luke 3:15 The people were waiting expectantly and were all wondering in their hearts if John might possibly be the Messiah.
The context seems not to say "the people" were all Judea, but the people listening to John.
John 8:2 the same, it even says "all the people gathered around him", not Judea or the universe. It is just like someone says to me "did you eat the apples" and I reply "I ate them all".
Luke 4:1 He was teaching in their synagogues, and everyone praised him.
"everyone" was obviously everyone in the synagogues. Like "I went to meet all the people in the Kingdom Hall".
Luke 11:37-41 While Jesus was speaking, a Pharisee asked him to dine with him, so he went in and reclined at table. The Pharisee was astonished to see that he did not first wash before dinner. And the Lord said to him, “Now you Pharisees cleanse the outside of the cup and of the dish, but inside you are full of greed and wickedness. You fools! Did not he who made the outside make the inside also? But give as alms those things that are within, and behold, everything is clean for you.
If the pharisees where acting clean both inside and outside, they were clean all over. Everything is within context of the spoken subject.
