Donald Trump's Feud With Ted Cruz Takes Nastier Turn

"For the sake of our party and country, we must move to overcome the divisiveness and vulgarity Donald Trump has brought into the political arena, or we will certainly lose our chance to defeat the Democratic nominee and reverse President Obama's failed policies."

"She also slammed Cruz for denying links with super-PACs supporting his campaign, arguing that such collaboration is typical on the campaign trail."

"The Republican primary has become a national disgrace. It is humiliating for the country for this bad soap opera to be unfolding in one of the nation's two major political parties. The Republican primary is now centered on Donald Trump's attacks on Ted Cruz's wife. Republicans have abandoned any illusions of talking about policy, and how they would run the country if elected. Ted Cruz was right to defend his wife, but in no universe should this conversation have any place in a presidential primary. Donald Trump has taken the national discourse to a new low."

This campaign has already been criticized by many for its lack of civility. How much nastier and how much uglier will the rivalry between Donald Trump and Ted Cruz become?
