Donald Trump is back at the Twitter machine, lashing out again at his closest competitor, Ted Cruz.
"It's time for Ted Cruz to either settle his problem with the FACT that he was born in Canada and was a citizen of Canada, or get out of race," Trump tweeted Monday morning, on the heels of Fox News polls released over the weekend that showed him with double-digit leads over Cruz in both Iowa and New Hampshire.
He's continuing to harp on it, probably, because the polls have shown that it works:
Donald Trump knows what he's doing when he repeatedly brings up this issue—36% of Cruz voters aren't aware yet that he wasn't born in the United States, and 24% of Cruz voters say someone born outside the country shouldn't be allowed to be President. So this issue has the potential to be a difference maker with the race persistently so close in Iowa.
That's a PPP polling memo from January 12. And now, according to a Fox News poll released this weekend, Trump is back up over Cruz by 11 points, 34 to 23 percent. Is it the birther issue, or have enough Iowans now been personally exposed to Cruz's loathsome personality?
