（兩個markers都係畀2 out of 4)
The total percentage for voting the democrats and the localists slightly decreased by 1%, changing from 56% in 2012 to 55% in 2016, while the total percentage for voting the pro-establishment slightly decreased by 3%, changing from 45% in 2012 to 40% in 2016. The percentage for voting the middle ground increased by 4%, changing from 1% to 5% in 2016. While the percentage for voting the democrats just slightly changed, the proportion for voting the relatively more radical ones (including both the radical-democrats and the localists) increased by 11%, changing from a total of 15% in 2012 to 26% in 2016.
我宜家睇返覺得最大問題可能係得冇compare晒每組自己嘅改變（漏咗traditional pan-democrats, radical-democrats同localists).
另一個問題係冇界定清楚
democrats=traditional pan-democrats+radical pan-democrats.
除此之外仲有咩可以改善？
