'It's costing the President': GOP pollster puts Trump on notice over major drop in support

Donald Trump is bleeding support among independents and swing voters, and one Republican pollster says he is concerned.

GOP pollster and communications strategist Frank Luntz appeared on CNN on Sunday, where he was asked about the outlet's polling showing Trump's falling numbers.

The change, Luntz said, is "significant."

He noted that most Americans still support the priorities of the Republican party, but are unhappy about how Trump is carrying it out.

"The agenda still has a majority support," he said, "But the way that it's being articulated is costing the president right now."

Luntz went on to warn Trump that he should change his messaging strategy on certain key issues, or face this polling problem becoming more significant and long-term.
