Trump made a Contract with America for his first 100 days. You ARE aware that HE is the one who made a big deal out of his first 100 days aren't you? So how did he score? Did he actually show up and do the work and keep his word? How?
Obama began to formally create his presidential footprint during his first 100 days. Obama quickly began attempting to foster support for his economic stimulus package, American Recovery and Reinvestment Act of 2009. The bill passed in the House on January 28, 2009, by a 244–188 vote, and it passed in the Senate on February 10 by a 61–37 margin.
So as you see, Rosie, the term "first hundred days" actually originated with FDR - info that would have been readily available to you had you spent 10-15 minutes doing a very small amount of research. Now we all get that you intensely dislike President Trump - LOUD AND CLEAR. But I'm starting to believe that you're so hell-bent on demonizing the guy that you won't let facts (or checking them) stand in your way. And this appears to be a theme in many of your questions.
And BTW, "Contract with America" is also nothing new - again a fact you could have discovered with a simple Google search...
The Contract with America was a document released by the United States Republican Party during the 1994 Congressional election campaign. Written by Newt Gingrich and Dick Armey, and in part using text from former President Ronald Reagan's 1985 State of the Union address, the Contract detailed the actions the Republicans promised to take if they became the majority party in the US House of Representatives for the first time in 40 years.
