だいぶ撒いとるしなあ means what?

Question

だいぶ - greatly? 撒く - spread? しなあ - ?

UPDATE: the context is the following. It's a scene from anime 'Your name'. The mayor is giving a speech in front of an audience. Then the focus is moved to a couple of people standing in the back among the crowd. A man says, "He's going to be reelected anyway". A woman says back to him だいぶ撒いとるしなあ. In the subtitles it is translated as "I heard he's been dishing out the pork". As far as I understand し here is used to creat a list? Like she's adding to the man's point. And なあ is just for emphasis? So "And (he's been) greatly spreading (rumors/lies?) (about himself?)

Answer 1

「だいぶ撒{ま}いとるしなあ。」

In the context of politicians running for elections (in small towns), 「撒{ま}く」 can usually mean just one thing -- "to go around giving citizens/voters things that have monetary value" in order to win their favor. The original meanings of the word are "to sprinkle", "to scatter", etc., so one could see the connection.

「だいぶ」 is an intensifier.

「し」 is used to give an example. In this case, it is one example of the reasons why he would be reelected.

「なあ」＝「な」. This is a sentence-ender for a light kind of declaration that also functions to seek agreement from the listener. It is similar to 「ね」 and 「ねえ」 in meaning.

Thus, an example translation would be something like:

"He sure has done a great deal of handing out stuff around us, hasn't he?"
