2010 Senate ballot
A sample ballot for the 2010 Colombian senate elections. Voters can vote in either Part A (the national district of 100 seats) or in Part B (for the 2 indigenous set-aside seats). Voters may not vote in both.
Voters mark the logo of their preferred party and then, if the party has open lists (most do), the voter has the option of voting for their preferred candidate by marking the number of that candidate--which is why campaign ads usually have a number by the candidate's name).
