I think a lot of Conservatives might want to reconsider this need to tear down Trump. Thanks to Trump moving the Overton Window back away from where the Leftist media has been pushing it for decades, a "President Cruz" rather then a "Former GOP Presidential Nominee Jeb Bush" is a real possibility in 2016.
The Overton window, also known as the window of discourse, is the range of ideas the public will accept. It is used by media pundits.[1][2] The term is derived from its originator, Joseph P. Overton (1960–2003),[3] a former vice president of the Mackinac Center for Public Policy,[4] who in his description of his eponymous window claimed that an idea's political viability depends mainly on whether it falls within the window, rather than on politicians' individual preferences.[5] According to Overton's description, his window includes a range of policies considered politically acceptable in the current climate of public opinion, which a politician can recommend without being considered too extreme to gain or keep public office.
There is not just a single window. There are a variety of windows, for different groups.
The windows of "politically acceptable" ideas for conservatives, independents, democrats are not the same.
Instead of "windows" which suggest squares or rectangles, the idea was put forth previously as a Venn diagram, or set diagram, or logic diagram.

Part of that task involves finding shared ideas, goals, interests, etc. That in turn involves converting, persuading, voters.
