The blue "two-third icon" should not be there!
That is a remnant from an old proposal

Code looks good so far

The marking of majorities look good so far. A few qestions/issues came up:

• In the dropdown-menu in the dialogue please change the order of majorities to this: no majority, absolute majority, two-thirds
• The calculation of absolute majority is correct. As discussed with @emanuelschuetze , the two-thirds majority should already be reached if exactly two-thirds or more yes votes were cast.
• Is it possible to include helptexts to the majority options in the dialogue? If so, for absolute majority it should be something like "Indicates if a majority of more than 50% was reached, dependent on the 100%-base" and for two-thirds "Indicates of majority of two-thirds or more was reaches, dependent on the 100%-base"
• When 100%-base "deactivated" is selected, the chart always has the x in the middle even if a majority would be reached, i.e. 100% yes votes. For this 100%-base the chart should never show the majority.
• I observed that the majorities don't work in assignment polls with the voting method "no per candidate". Is that intentional? I think it's okay but want to make sure it's not an oversight.
