In Flake's piece, titled "My Party Is in Denial About Donald Trump", the senator lays out a list of grievances against the president.
And while Pence - a former lawmaker in the House - acts as a bridge to Congress, it's far from clear how much the president is seeking his advice.
"It is going to be important, especially in the primary, to remind people that Senator Flake is a fiscal hawk", said O'Daniel, now a political consultant in Arizona but not currently involved in Flake's campaign. In a section titled "My Party Is In Denial About Donald Trump", the senator accuses Republican lawmakers of "passively" observing the "unfolding drama" of the current presidency. McConnell told reporters he hadn't read Flake's book and refused to comment on the Arizona senator's censure of the President and his own party leaders. "And I think, furthermore, we need to realize that it's not just the political leaders that are showing dysfunction, it's the people in the country, the partisans, who demand certain things, as John McCain said in a very bombastic way". "He chose to express his, and some members may choose not to express theirs".
"In our poll taken immediately following President Trump's inauguration, 31 percent of independent voters disapproved of him", said Morning Consult Co-founder and Chief Research Officer Kyle Dropp.
To illustrate his point, Flake pointed out Obamacare was pushed through by only the Democrats, and now only Republicans are struggling to repeal it.

He's even written a new book about it, and other things presumably, ironically titled "Conscience of a Conservative.' If the title sounds vaguely familiar, it's because "Mr".
The only reference Flake makes to now-disgraced former Speaker J. Dennis Hastert is in a story about a time Flake forced a vote on stripping a Hastert earmark, even after being informed by a journalist that the IL project originated with the speaker.
Flake told CNN's Jake Tapper on Tuesday that senators should not simply go along with everything a president from their own party supports. On one foreign policy issue, Cuba, Flake has been at odds with Trump, steadfastly supporting rapprochement with Havana.
The aptly named Flake just wrote a book titled "Conscience of a Conservative" and if that sounds familiar, it's because Barry Goldwater wrote it first. He added, "You know, somehow conservatism has become being mean or loud, and you can't enact conservative policy if you act that way". He said he's particularly concerned conservative tenets of free trade and limited government have been lost to a national leadership that is erratic, mean-spirited and self-serving. Take a look at him selling his book. Flake asks. "If by 2017 the conservative bargain was to go along for the very bumpy ride because with congressional hegemony and the White House we had the numbers to achieve some long-held policy goals-even as we put at risk our institutions and our values-then it was a very real question whether any such policy victories wouldn't be Pyrrhic ones".
Asked whether he was anxious that by writing the book, he would put his Senate career in jeopardy, Flake said he stood behind his decision.
"I think with round-the-clock media coverage and social media now, it all kind of drives us apart". In mid-July, two top White House officials published an op-ed calling the CBO's methodology for estimating the impact of Republican health care legislation "fundamentally flawed".
