DOMINUS said"Already planning?" I don't think so. The "Repube Plan" has been in place since Pres. Obama won the presidency in 2008. You might want to ask McConnell and his cabal about that, but given their history of living in alternate reality they're simply going to deny it just like their leader, the illusionist-cum-fictionist-cum-KKK royalty Trump. It's the same tired plan, tweaked to make it appear more current. But make no mistake, they will use this "plan" for the rest of the Republican Party's life because there will never be another Repube president again.
Possibly true considering shifting demographics alone--which could make you right on the presidency, and also possibly a majority in the house of reps eventually as growing states like Florida turn blue--so I think the notion here is for the GOP to attack at the level of the Senate where there will not just remain 2 per state but that in a country where new population tends to congregate. So even with shifting demographics, by how populations settle, they could either keep the Senate outright or at least a measurable percent, maybe enough to block legislation. Thus the article's note of 60 which the following elucidates upon:
http://www.senate.gov/artandhistory/history/common/briefing/Filibuster_Cloture.htm in 1917, senators adopted a rule (Rule 22), at the urging of President Woodrow Wilson, that allowed the Senate to end a debate with a two-thirds majority vote, a device known as "cloture." The new Senate rule was first put to the test in 1919, when the Senate invoked cloture to end a filibuster against the Treaty of Versailles. Even with the new cloture rule, filibusters remained an effective means to block legislation, since a two-thirds vote is difficult to obtain. Over the next five decades, the Senate occasionally tried to invoke cloture, but usually failed to gain the necessary two-thirds vote. Filibusters were particularly useful to Southern senators who sought to block civil rights legislation, including anti-lynching legislation, until cloture was invoked after a 60 day filibuster against the Civil Right Act of 1964. In 1975, the Senate reduced the number of votes required for cloture from two-thirds to three-fifths, or 60 of the current one hundred senators.
And here's the Senate's current seating chart...
http://www.senate.gov/history/partydiv.htm114th Congress (2015-2017)
Majority Party: Republican (54 seats)
Minority Party: Democrat (44 seats)
Other Parties: 2 Independents (both caucus with the Democrats)
Total Seats: 100
So even if they finally lose the judicial branch which they've held for more than four decades now -- all the while screaming how liberal judges are activists (lol the CONservatives are such scum) -- and lose the presidency (again) (and again and again and again), until we flood the flyovers with Mexicans and Canadians, they've still got half a branch to check powers of the other two. Well, two and a half lol. Still, it seems the fat lady won't sing until she's had her fill of tacos and snow cones.
