Question: In what political party does Paul Ryan and "The Path to Prosperity Proposal" both come from?

Context paragraphs:
Paul Ryan: Paul Davis Ryan Jr. ( ; born January 29, 1970) is an American politician who is the 54th and current Speaker of the United States House of Representatives.  He was the Republican Party nominee for Vice President of the United States, running alongside former Governor Mitt Romney of Massachusetts, in the 2012 election.

A Better Way: A Better Way is a conservative agenda for U.S. governance, crafted by Speaker of the House Paul Ryan as well as Kevin Brady, chairman of the House Ways and Means Committee.  Ryan calls the six-point plan "a complete alternative to the Left's agenda".  Shortly after the United States elections, 2016, Speaker Ryan said that the plan, described by Reuters as an "aggressive Republican legislative agenda", provides a blueprint for laws he expects to spearhead in the Republican congress in cooperation with the Republican Trump administration.  For someone other than the party's nominee to direct the party's agenda in a presidential election year has been termed "a rare move".

The Path to Prosperity: The Path to Prosperity: Restoring America's Promise was the Republican Party's budget proposal for the United States federal government in the fiscal year 2012.  It was succeeded in March 2012 by "The Path to Prosperity: A Blueprint for American Renewal", the Republican budget proposal for 2013.  Representative Paul Ryan, Chairman of the House Budget Committee, played a prominent public role in drafting and promoting both "The Path to Prosperity" proposals, and they are therefore often referred to as the Ryan budget, Ryan plan, Ryan proposal, etc.

Democratic Party of Albanians: The Democratic Party of Albanians (Albanian: "Partia Demokratike Shqiptare" ; Macedonian: Демократска партија на Албанците , "Demokratska Partija na Albancite") or DPA is a political party of the ethnic Albanians in the Republic of Macedonia.  The DPA is a merger of the Party for Democratic Prosperity of Albanians (PDPA) and the People's Democratic Party (NDP) which took place in June 1997.  The former party was established in 1994 after some radical members of the Party for Democratic Prosperity, led by Menduh Thaçi and Arbën Xhaferi, left the PDP and the latter party was founded in August 1990 as a more radical opponent of the PDP.

The Agenda Project: America the Beautiful: In May 2011, The Agenda Project, New York-based non-profit political organization, released its “America the Beautiful” campaign, also known as “Granny off the Cliff.”  The video was created in response to Rep. Paul Ryan’s proposed Medicare cuts, as part of The Path to Prosperity, the Republican Party’s long-term budget proposal.

Aboriginal Peoples Party of Canada: The Aboriginal Peoples Party of Canada (APP) is a Canadian political party that was founded in 2005.  The party was conceived by University of Lethbridge student Myron Wolf Child.  It held its founding meeting on August 21, 2005, in St. Albert, Alberta.  The APP was headed by interim leader Bill Montour, a former Chief of the Six Nations Reserve in Ontario.  In October 2005, the party had 122 confirmed members, just less than half the number needed to register as an official party in Canada.  In late October 2005, the APP sought to unite with the First Peoples National Party of Canada which also had fewer than the number of confirmed members needed to become a registered political party.  The First Peoples National Party of Canada became an eligible political party on December 6, 2005.  Whether or not this was accomplished through a merger with the APP is unclear.  If this is the case, the APP no longer exists, but, as one of the stipulations of a possible merger was that a name for the new party would be determined at the party's first convention, it is possible that the name Aboriginal Peoples Party of Canada will come into usage again.

Federation Party: The Federation Party was Fiji's first formal political party.  The Citizens Federation, which had won three of the four seats reserved for Indo-Fijians at the 1963 elections, decided to formalize its role as a political party, which was officially founded on 21 June 1964 with A. D. Patel as President and Sidiq Koya as Vice-President.  The merger took place in time for the party to participate in the 1965 constitutional conference which was called to map out a path towards independence from the United Kingdom.  In 1968, the Federation Party merged with the National Democratic Party to form the National Federation Party, which is now (2015) the oldest political party in Fiji still in existence.

It was formed on 25 July 2007 as a merger of the All People's Party and the Bhutan People's United Party, which were both short-lived.  The working committee of the merged entity, headed by the former home minister, Jigmi Yoezer Thinley, decided on the name for the new party.  On 15 August 2007, Jigmi Yoezer Thinley was elected president of the party, and the party applied for registration, thus becoming the second political party in Bhutan to do so.  On 2 October 2007, the Election Commission of Bhutan registered the party.  On 24 March 2008, the party won the first general election held in Bhutan.  The party secured 45 of the 47 seats to the National Assembly.
