Ted Cruz, the Republican nominee for U.S. Senate, told Meet the Press moderator David Gregory that he's "thrilled with the pick of Paul Ryan" as Mitt Romney's running mate. "I think the biggest Ryan effect is that this race is going to focus on issues. ... If this presidential race focuses on issues — if it focuses on the economy, on President Obama's abysmal economic record — Republicans win. If it's a battle of personalities, Republicans will lose."
