Zevran pipes up if he's in the party when you speak with Harrowmont's second. Basically he says Harrowmont is weak if he's cowering behind others. Bhelen is cowering behind others too, but he's also blackmailing people and threatening their families so natch he's the 'strong choice'.
Considering said blackmail, threats and forgery, there's plenty of reason to be dubious on whether Bhelen's the 'trustworthy choice'.
Whoever said political campaigners are obliged to keep their promises?
That I don't think was Zevran's main point. Zevran points out that Harrowmont's own men won't fight for him and that Harrowmont himself is weak. This is true, not only in the proving. When you enter Orzammar for the first time and you see that confrontation between Harrowmont and Bhelen where one of Bhelen's men kills the town guard, knocking harrowmont over, his guards run away while Harrowmont is still on the ground, instead of protecting him until he can get away.
Anyway, here's what Zevran says:
Zevran: *Chuckle* And this is to be your king? One who cannot keep his own men from running like frightened children? (Amused.)
Dulin: Lord Harrowmont does not use threats or intimidation to motivate his men. He leads by example. (defending his hero)
Zevran: Ah, I see. So it's his example they follow as they cower from this Prince Bhelen? (mocking)
Dulin: How dare you slander Lord Harrowmont! (Angry)
Zevran: Why should we ally ourselves with someone too scared even to grant us an audience? (Umimpressed.)
Warden: Your snide comments are not helping.
Zevran: Were I you I would seek a stronger king than this Harrowmont. (Dismissive)
If Harrowmont weren't bribing people, then Bhelen would not be able to sway away those votes through forgery.
Orzammar politics are dirty -- you learn that from the start.
