Magneto would stop him unless he decides to join him.
He could get pretty far actually, by taking control of very powerfull beings, killing most of his potential oppostion in their sleep before they realize what's going on and planting hypnotic messages in the minds of powerfull humans. If he is subtle and crafty, he could be influencing the world's political and economical landscape on a very large scale in a short while. But there's still too many people guarded against TP and too much anti-tp techonology out there. I don't think he manages to actually conquer the earth, but could become a major global player with relative ease if he's smart about it. Even after he is exposed, I can see him going into hiding and continuing to play from the shadows.
This actually would be a pretty interesting take on the character, specially if he starts subverting the world out of an altruistic desire to make it better, a Millar's Authority version of chuck would be awesome. I always felt the character's potential is very underused.
Anyway, in a year, his influence could spread to the point he is the most powerfull man on earth, 1 month ain't gonna do it though.
