I don't think they are the same thing. "We will" is a stronger statement in intent than "We are going." "We will elect Trump!" versus "We are going to elect Trump!" may refer to the same election, but the former would be followed by a stronger statement: We will elect Trump! It's great! We are going to elect Trump! I'm excited! I don't think it's a hard and fast rule, but if people use the future tense, it's more of a personal or indefinite statement, and the present tense is more universal and definite one. "We elect Trump tomorrow." is something that misses this. You remove the individual ability to affirm or weaken the statement. I don't know much about Dutch and English, but I'd wonder if many Dutch people fluent in English have problems with getting taken too definitely or being seen as pushy.
