The meaning of and difference between ～を中心に and ～をめぐって


What is the meaning of and difference between `～を中心に` and `～をめぐって`?

Space ALC defines
[`～を中心に`](http://eow.alc.co.jp/%E3%82%92%E4%B8%AD%E5%BF%83%E3%81%AB/UTF-8/) as
"with a focus on" and
[`～をめぐって`](http://eow.alc.co.jp/%E3%82%92%E3%82%81%E3%81%90%E3%81%A3%E3%81%A6/UTF-8/)
as "centering on", but I'm having trouble figuring out the meaning and
difference in usage of the two.

I saw the following example sentence for `～を中心に` in the (old) JLPT2 `完全マスター`,
which [JGram](http://jgram.org/pages/viewOne.php?tagE=wochuushinni)
interpreted slightly differently to me:

> 駅 **を中心に** 沢山の商店が集まっている。  
>
>
>   * My first interpretation: " _In_ the station there are lots of stores
> grouped together."  
>
>   * JGram's interpretation (which I now think is more accurate): " _Centered
> around_ the station there are many stores."
>

The way I now understand it is that `～を中心に` means more
"([focused/centered/revolving]) _around_ " rather than " _in_ the center of
something". Would this explanation be accurate?

I've also encountered `～をめぐって` a couple of times. The following example I read
today in the April 2012 edition of `中央公論`:

> 政党というものは、単に選挙 **をめぐって** 候補者をリクルートし、有権者へ働きかけて動員するための組織ではない。  
>  My attempted translation: "A political party isn't an organization which is
> simply about recruiting candidates _focusing on_ elections and encouraging
> mobilization of voters."

If I switched `をめぐって` with `を中心に`, would it have the same or similar meaning?
What would the differences in nuance be between the two?




They have pretty much different meanings. `中心に` adds blur. It means `centered
around`. `めぐって` means 'regarding', and implies some kind of a debate. They are
in general not interchangable.

> 駅を中心に沢山の商店が集まっている  
>  'many stores are gathered around the the station'  
>  More literally: 'many stores are gathered with its center being the
> station'
>
> 駅をめぐって沢山の商店が集まっている  
>  'many store (owner)s are gathered {regarding, to talk about} the station'
>
> 選挙(の時期)を中心に候補者をリクルートする  
>  'hire candidates mostly at around the time of an election'  
>  More literally: 'hire candidates with its center being the time of an
> election'
>
> 選挙をめぐって候補者をリクルートする  
>  'hire candidates {regarding, for} an election'
