The president was referring to the daily tracking poll by Rasmussen Reports, which surveys 500 likely voters every night and then produces a rolling average to come up with the president's daily approval rating.
Some signs of waning enthusiasm, though not outright defection, are evident in the most recent approval numbers.
Fifty-one percent of those surveyed between June 2 and June 11 said they disapprove of the president's job performance.
Only 41 percent of Republicans are happy with the how things are going. But 40 percent of Republicans chose a non-judgment (either "don't know" or "neither favorable or unfavorable"). "But Texas Republicans are holding steady". That contention aligns with the views of Republican voters in Texas. Among Tea Party Republicans, Abbott gets approving nods from 90 percent; Patrick from 78 percent.
The failure of those expectations during the campaign are now fully in evidence. He said Trump's statement on Twitter Friday was specifically in response to a story in The Washington Post about the expanding probe into Russia's election meddling.
This is the first time Trump has hit 50 percent in the poll since late April. Forty-seven percent said he was incompetent, while 46 percent said he was competent.
What do you think of President Trump's performance and the FBI's handling of the Russian Federation investigation?
This President seems to have an infatuation with his predecessor, so much so that he has lied repeatedly about him and continues to try and undo everything that Barack Obama had accomplished over the past 8 years. An average of the major national polls compiled by Real Clear Politics put Obama's approval rating on June 16, 2009, at 59.6%.
Yet the situation is a precarious one for Republican elected officials, who have been delivered to the brink of political disaster by continuing storm of suspicions, investigations and intransigent responses defining Trump's presidency thus far.
