The top Republican in the Senate was the first to throw down the gauntlet this week, saying back home in Kentucky that it was Trump's political inexperience that led to him setting "excessive expectations" over wanting to speedily repeal Obamacare. It began with a little Twitter prodding yesterday in response to McConnell's criticism of Trump's expectations, and his penchant for setting arbitrary deadlines that have nothing to do with the legislation in question.
"[Mitch McConnell] must have needed another 4 years - in addition to the 7 years - to repeal and replace Obamacare".
Trump has been sniping at McConnell for several days on Twitter, a reaction to McConnell's earlier remarks that the president was new to Washington and doesn't realize how hard it is to pass legislation. "I think he had excessive expectations about how quickly things happen in the democratic process". Trump tweeted from his vacation in New Jersey. "Obviously there's some frustration", White House press secretary Sarah Huckabee Sanders told reporters Thursday.
Sara Fagen, who served as a chief strategist to President George W. Bush's reelection campaign in 2004, compared Trump's McConnell attack unfavorably to the President's other headline-making comment of the past two days.
After firing off another tweet at McConnell on Thursday morning, the president also retweeted a poll that asks followers who made for a better president - himself or former President Barack Obama.
Also joining the fray was Fox News Host Sean Hannity, a close Trump ally.
Trump has failed to notch up a major legislative win since taking office in January, although Republicans control both the Senate and House of Representatives.
So there you have it: Republicans have offered up four takes on repeal and replace and none of them increase the number of insured Americans or keep the same numbers as Obamacare. Trump was nearing the end of that contentious presidential primary, that featured several members of McConnell's caucus exchanging fiery rhetoric with the eventual GOP nominee. But Mr Trump has continued to tweet about the issue, and wrote that "unless the Republican Senators are total quitters, Repeal & Replace is not dead!"
