Jason Johnson, a political analyst, told Al Jazeera that the Republican presidential competition had become a “two-man race” between the more conservative Perry and Romney.
“Everybody else looked like wallpaper,” he said.
He said Perry was “not a very good debater” and described Romney’s performance as “reasonable”.
“It was his job to go into this and say ‘this is a two-man race, between the extreme wing of the party and the moderate part of the party.
“But he didn’t do a good job in establishing why people should pick a moderate instead of Rick Perry, who’s a true believer”.
