Do you completely trust what either candidate will say in this setting?

No. Some candidates make promises just to make themselves sound more appealing, nothing is set in stone unless they sign a paper with their signatures before hand (I'm not sure they're technically allowed in many cases.) Like for example one of the presidents (I won't name any names so that we won't get into a political debate) had promised and swore that they'd do something but once they'd won presidency, they'd completely deleted it from their page and acted as though it hadn't happened, stating that they'd just changed their mind!
Good luck, rockstar! I hope you pass. (;
