Erica Grieder explains the most bellicose member of the Senate's new arrivals:
[A]s he climbs the political ladder, he seems destined to annoy some more people along the way. He might even take a shot at the presidency some day. If he does, he might come across as too wonkish and too aggressive to connect with voters. “Belligerent egghead” has rarely been a winning brand in presidential politics. (Just ask Newt Gingrich.) In terms of foreign policy, though, polling shows that Republicans around the country share some of Cruz’s concerns; they are, for example, somewhat skeptical of international cooperation. And to date, at least, it doesn’t seem that Cruz’s controversies have caused him any personal trouble; in January, Public Policy Polling found that he had a higher net approval rating than either Perry or Cornyn. If he wants to have a greater role in national politics, which seems likely, there's clearly an audience.
